The official, canonical postActiv repository. http://www.postactiv.com
The main configuration file for StatusNet (excepting configurations for
dependency software) is config.php in your postActiv directory. If you edit any
other file in the directory, like
lib/default.php (where most of the defaults
are defined), you will lose your configuration options in any upgrade, and you
will wish that you had been more careful.
Starting with version 0.9.0, a Web based configuration panel has been added to postActiv. The preferred method for changing config options is to use this panel.
A command-line script, setconfig.php, can be used to set individual configuration options. It's in the scripts/ directory.
Starting with version 0.7.1, you can put config files in the /etc/postActiv/ directory on your server, if it exists. Config files will be included in this order:
/etc/postActiv/statusnet.php - server-wide config
/etc/postActiv/<servername>.php - for a virtual host
/etc/postActiv/<servername>_<pathname>.php - for a path
INSTALLDIR/config.php - for a particular implementation
Almost all configuration options are made through a two-dimensional associative array, cleverly named $config. A typical configuration line will be:
$config['section']['option'] = value;
For brevity, the following documentation describes each section and option.
This section is a catch-all for site-wide variables.
name (string, required, default "Another postActiv Instance"): the name of
your site, like 'YourCompany Microblog'.
server (string, required, default null): the server part of your site's URLs,
path (string, required, default ''): The path part of your site's URLs, like
'statusnet' or '' (installed in root).
fancy (string, default false): whether or not your site uses fancy URLs (see Fancy URLs
logfile (string, default './'): full path to a file for StatusNet to save
logging information to. You may want to use this if you don't have access
logdebug (boolean, default false): whether to log additional debug info like
backtraces on hard errors.
locale_path (string, default null): full path to the directory for locale
data. Unless you store all your locale data in one place, you probably
don't need to use this.
language (string, default "en_us"): default language for your site. Defaults
to US English. Note that this is overridden if a user is logged in and has
selected a different language. It is also overridden if the user is NOT
logged in, but their browser requests a different langauge. Since pretty
much everybody's browser requests a language, that means that changing
this setting has little or no effect in practice.
languages (array, default null): A list of languages supported on your site.
Typically you'd only change this if you wanted to disable support for one or
"unset($config['site']['languages']['de'])" will disable support for German.
theme (string, default 'default'): Theme for your site (see Theme section).
Two themes are provided by default: 'default' and 'stoica' (the one used by
Identi.ca). It's appreciated if you don't use the 'stoica' theme except as
the basis for your own.
broughtbyurl (string, default null): name of an organization or individual
who provides the service. Each page will include a link to this name in the
footer. A good way to link to the blog, forum, wiki, corporate portal, or
whoever is making the service available.
broughtby (string, default null): text used for the "brought by" link.
timezone (string, default 'UTC'): default timezone for message display. Users
can set their own time zone. Defaults to 'UTC', which is a pretty good
closed (boolean, default false): If set to 'true', will disallow registration
on your site. This is a cheap way to restrict accounts to only one
individual or group; just register the accounts you want on the service,
then set this variable to 'true'.
inviteonly (boolean, default false): If set to 'true', will only allow
registration if the user was invited by an existing user.
private (boolean, default false): If set to 'true', anonymous users will be
redirected to the 'login' page. Also, API methods that normally require no
authentication will require it. Note that this does not turn off
registration; use 'closed' or 'inviteonly' for the behaviour you want.
notice (string, default null): A plain string that will appear on every
page. A good place to put introductory information about your service, or
info about upgrades and outages, or other community info. Any HTML will be
logo (string, default null): URL of an image file to use as the logo for the
site. Overrides the logo in the theme, if any.
ssllogo (string, default null): URL of an image file to use as the logo on
SSL pages. If unset, theme logo is used instead.
ssl (enum['always','sometimes','never'], default 'never'): Whether to use SSL
and https:// URLs for some or all pages.
Possible values are 'always' (use it for all pages), 'never' (don't use it for any pages), or 'sometimes' (use it for sensitive pages that include passwords like login and registration, but not for regular pages).
sslproxy (boolean, default false): Whether to force GNUsocial to think it
is HTTPS when the server gives no such information. I.e. when you're using
a reverse proxy that adds the encryption layer but the webserver that runs
PHP isn't configured with a key and certificate.
sslserver (string, default null): use an alternate server name for SSL URLs,
like 'secure.example.org'. You should be careful to set cookie parameters
correctly so that both the SSL server and the "normal" server can access
the session cookie and preferably other cookies as well.
dupelimit (integer, default 60): minimum time allowed for one person to say
the same thing twice. Default 60s. Anything lower is considered a user or
textlimit (integer, default 0): default max size for texts in the site. Can
be fine-tuned for notices, messages, profile bios and group descriptions.
Zero indicates no limit.
doc_path (string, default null): local filesystem path to UI documentation
mail_path (string, default null): local filesystem path to the mail
used by postActiv.
This section is a reference to the configuration options for
The ones that you may want to set are listed below for clarity.
database (string, required, default null): a DSN (Data Source Name) for your
postActiv database. This is in the format
'protocol://username:password@hostname/databasename', where 'protocol' is '
mysql' or 'mysqli' (or possibly 'postgresql', if you really know what
you're doing), 'username' is the username, 'password' is the password,
ini_yourdbname (string, default null): if your database is not named 'statusnet',
you'll need to set this to point to the location of the statusnet.ini file.
Note that the real name of your database should go in there, not literally
db_driver(enum['DB','MDB2'], default null): You can try changing this to
'MDB2' to use the other driver type for DB_DataObject, but note that it
breaks the OpenID libraries, which only support PEAR::DB.
quote_identifiers(boolean, default false): Set this to true if you're using
type (enum["mysql", "postgresql"], default 'mysql'): Used for certain
database-specific optimization code. Assumes mysql if not set. MySQL also
covers MySQLi and MariaDB.
mirror (array, default null): you can set this to an array of DSNs, in the
format of the above 'database' value. If it's set, certain read-only
actions will use a random value out of this array for the database, rather
than the one in 'database' (actually, 'database' is overwritten). You can
offload a busy DB server by setting up MySQL replication and adding the
slaves to this array. Note that if you want some requests to go to the
'database' (master) server, you'll need to include it in this array, too.
utf8 (boolean, true): whether to talk to the database in UTF-8 mode. This is
the default with new installations, but older sites may want to turn it off
until they get their databases fixed up. See "UTF-8 database" above for
schemacheck (enum["runtime", "script"], default "script"): when to let
plugins check the database schema to add tables or update them. 'runtime'
can be costly (plugins check the schema on every hit, adding potentially
several db queries, some quite long), but not everyone knows how to run a
script or has the access in their hosting environment to do so. If you can,
set this to 'script' and run scripts/checkschema.php whenever you install
or upgrade a plugin.
There are a variety of site-wide filtering options which can be used to keep objectionable content off the server.
banned_instances - hubsub callbacks and salmon notices from these instances
will be discarded, effectively blocking these servers from federating with
your server. It should be noted this won't stop them from scraping feeds,
subscription_filter - a Perl-compatible regular expression which is used to
filter incoming subscriptions - users matching this regular expression will
not be able to subscribe to users on this server, they will get an
authorization error. Care should be taken with any PCRE put in here since
it can cause false positives.
By default, postActiv sites log error messages to the syslog facility. (You can override this using the 'logfile' parameter described above).
appname (string, default
'postActiv'): The name that postActiv uses to log
messages. By default it's "postActiv", but if you have more than one
installation on the server, you may want to change the name for each
instance so you can track log messages more easily.
facility (string, default
'LOG_USER'): what syslog facility to use. Only set
this if you know what syslog is and have a good reason to change it.
You can configure the software to queue time-consuming tasks, like sending out SMS email or XMPP messages, for off-line processing. See 'Queues and daemons' above for how to set this up.
enabled (boolean, default false): Whether to uses queues.
daemon (boolean, default false): Wather to use queuedaemon. False means
you'll use OpportunisticQM plugin.
subsystem (enum["db", "stomp", "redis"], default 'db'): Which kind of queueserver to
use. Values include "db" for our hacked-together database queuing (no
other server required), "stomp" for a stomp server, and "redis" for a Redis
threads (int): How many queue "threads" (actually processes) to run. Defaults to
number of cpu cores in unix-like systems or 1 on other OSes.
items_to_handle (int): How many items to handle before a daemon process exits.
Default to unlimited.
stomp_server (string, default null): "broker URI" for stomp server.
Something like "tcp://hostname:61613". More complicated ones are possible;
see your stomp server's documentation for details.
queue_basename (string, default null): a root name to use for queues (stomp
only). Typically something like '/queue/sitename/' makes sense. If running
multiple instances on the same server, make sure that either this setting
or $config['site']['nickname'] are unique for each site to keep them
stomp_username (string, default null): username for connecting to the stomp
stomp_password (string, default null): password for connecting to the stomp
stomp_persistent (boolean, default true): Keep items across queue server
restart, if enabled. Note: Under ActiveMQ, the server configuration
determines if and how persistent storage is actually saved.
If using a message queue server other than ActiveMQ, you may need to disable this if it does not support persistence.
stomp_transactions (boolean, default true): use transactions to aid in error
detection. A broken transaction will be seen quickly, allowing a message to
be redelivered immediately if a daemon crashes.
If using a message queue server other than ActiveMQ, you may need to disable this if it does not support transactions.
stomp_acks (boolean, default true): send acknowledgements to aid in flow
control. An acknowledgement of successful processing tells the server we're
ready for more and can help keep things moving smoothly.
This should not be turned off when running with ActiveMQ, (it breaks if you do), but if using another message queue server that does not support acknowledgements you might need to disable this.
stomp_base64 (boolean, default false): whether to encode the queue item in
base64. This is needed for some queue servers such as RabbitMQ to avoid
encountering control characters.
stomp_properties (array, default null): additional headers to pass to STOMP
redis_socket_location (string, default null): Unix domain socket location for
Redis. If specified, the TCP settings below be disabled.
redis_host (string, default null): Hostname for Redis host.
redis_port (integer, default 6379): Port number for Redis daemon.
redis_namespace (string, default null): Prefix namespace for all Redis entries.
redis_retries (integer, default 10): How many times a queue item will be handled
before being dropped.
redis_expiration (integer, seconds, default: 86400/1 day): How long a queue item
will sit in Redis before being dropped.
softlimit (integer): an absolute or relative "soft memory limit"; daemons
will restart themselves gracefully when they find they've hit this amount
of memory usage. Defaults to 90% of PHP's global memory_limit setting.
inboxes (boolean, default true): delivery of messages to receiver's inboxes
can be delayed to queue time for best interactive performance on the
sender. This may however be annoyingly slow when using the DB queues, so
you can set this to false if it's causing trouble.
breakout (array, default null): for stomp, individual queues are by default
grouped up for best scalability. If some need to be run by separate daemons,
etc they can be manually adjusted here.
Default will share all queues for all sites within each group. Specify as <group>/<queue> or <group>/<queue>/<site>, using nickname identifier as site. 'main/distrib' separate "distrib" queue covering all sites 'xmpp/xmppout/mysite' separate "xmppout" queue covering just 'mysite'
max_retries (integer, default 10): for stomp, drop messages after N failed
attempts to process.
dead_letter_dir (string, default null): for stomp, optional directory to dump
data on failed queue processing events after discarding them.
stomp_no_transactions (boolean, default false): for stomp, the server does
not support transactions, so do not try to user them. This is needed for
stomp_no_acks (boolean, default false): for stomp, the server does not
support acknowledgements so do not try to user them. This is needed for
The default license to use for your users notices. The default is the Creative Commons Attribution 3.0 license, which is probably the right choice for any public site. Note that some other servers will not accept notices if you apply a stricter license than this.
As of 2016, this is largely disregarded in the Fediverse -mb
type (enum["cc", "allrightsreserved", "private"], default 'cc'): one of
'cc' (for Creative Commons licenses), 'allrightsreserved' (default
copyright), or 'private' (for private and confidential information).
owner (string, default 'contributors'): for 'allrightsreserved' or
'private', an assigned copyright holder (for example, an employer for a
url (string, default null): URL of the license, used for links.
title (string, default null): Title for the license, like 'Creative Commons
image (string, default null): URL of a button shown on each page for the
This is for configuring out-going email. We use PEAR's Mail module, see: http://pear.php.net/manual/en/package.mail.mail.factory.php
backend (enum["mail", "sendmail", "smtp"], default 'mail'): The backend to
use for mail. While this defaults to PEAR mail, we recommend SMTP where your
setup supports it as it is of the three the more difficult one for script
exploits to abuse (relatively speaking - they all have potential problems.)
params (array, default null): if the mail backend requires any parameters,
you can provide them in an associative array.
templates_path (string, default null): alias for
This is for configuring nicknames in the service.
blacklist (array, default null): an array of strings for usernames that
may not be registered. A hard-coded default array exists for strings that
are used by postActiv (e.g. 'doc', 'main', 'avatar', 'theme') but you may
want to add others if you have other software installed in a subdirectory
of postActiv or if you just don't want certain words used as usernames.
featured (array, default null): an array of nicknames of 'featured' users of
the site. Can be useful to draw attention to well-known users, or
interesting people, or whatever.
For configuring avatar access.
dir (string, default './avatar'): Directory to look for avatar files and to
put them into. Defaults to avatar subdirectory of install directory; if
you change it, make sure to change path, too.
path (string, 'default './avatar'): Path to avatars. Defaults to path for
avatar subdirectory, but you can change it if you wish. Note that this will
be included with the avatar server, too.
server (string, default null): If set, defines another server where avatars
are stored in the root directory. Note that the 'avatar' subdir still has
to be writeable. You'd typically use this to split HTTP requests on the
client to speed up page loading, either with another virtual server or
with an NFS or SAMBA share. Clients typically only make 2 connections to a
single server at a time
so this can parallelize the job.
ssl (boolean, default null): Whether to access avatars using HTTPS. Defaults
to null, meaning to guess based on site-wide SSL settings.
For configuring the public stream.
localonly (boolean, default true): If set to true, only messages posted by
users of this service (rather than other services, filtered through
OStatus) are shown in the public stream. Default true.
blacklist (array, default null): An array of IDs of users to hide from the
public stream. Useful if you have someone making excessive Twitterfeed
posts to the site, other kinds of automated posts, testing bots, etc.
autosource (array, default null): Sources of notices that are from automatic
posters, and thus should be kept off the public timeline.
server (string, default null): Like avatars, you can speed up page loading
by pointing the theme file lookup to another server (virtual or real).
The default of null will use the same server as PA.
dir (string, default "./themes"): Directory where theme files are stored.
Used to determine whether to show parts of a theme file. Defaults to the
theme subdirectory of the install directory.
path (string, default null): Path part of theme URLs, before the theme name. Relative to the
theme server. It may make sense to change this path when upgrading,
(using version numbers as the path) to make sure that all files are
reloaded by caching clients or proxies. Defaults to null,
which means to use the site path + '/theme'.
ssl (boolean, default null): Whether to use SSL for theme elements. Default
is null, which means guess based on site SSL settings.
sslserver (string, default null): SSL server to use when page is
HTTPS-encrypted. If unspecified, site ssl server and so on will be used.
sslpath (string, default null): If sslserver if defined, path to use when
page is HTTPS-encrypted.
server (string, default null): You can speed up page loading by pointing the
theme file lookup to another server (virtual or real). Defaults to NULL,
meaning to use the site server.
which means to use the site path + '/js/'.
Default is null, which means guess based on site SSL settings.
sslserver (string, default null): SSL server to use when page is HTTPS-
encrypted. If unspecified, site ssl server and so on will be used.
sslpath (string, default null): If sslserver if defined, path to use when
page is HTTPS-encrypted.
bustframes (boolean, default true): If true, all web pages will break out of
framesets. If false, can comfortably live in a frame or iframe... probably.
For configuring the XMPP sub-system.
enabled (boolean, default false): Whether to accept and send messages by
XMPP. Default false.
server (string, default null): Server part of XMPP ID for update user.
port (integer, default 5222): Connection port for clients.
user (string, default null): Username for the client connection. Users will
receive messages from 'user'@'server'.
resource: a unique identifier for the connection to the server. This
is actually used as a prefix for each XMPP component in the system.
password: password for the user account.
host: some XMPP domains are served by machines with a different
hostname. Set this to the correct hostname if that's the
case with your server.
encryption: Whether to encrypt the connection between StatusNet and the
XMPP server. Defaults to true, but you can get
considerably better performance turning it off if you're
connecting to a server on the same machine or on a
debug: if turned on, this will make the XMPP library blurt out all of
the incoming and outgoing messages as XML stanzas. Use as a
last resort, and never turn it on if you don't have queues
enabled, since it will spit out sensitive data to the browser.
public: an array of JIDs to send all notices to. This is useful for
participating in third-party search and archiving services.
For configuring invites.
enabled: Whether to allow users to send invites. Default true.
Miscellaneous tagging stuff.
dropoff: Decay factor for tag listing, in seconds. Defaults to exponential decay over ten days; you can twiddle with it to try and get better results for your site.
Settings for the "popular" section of the site.
dropoff: Decay factor for popularity listing, in seconds. Defaults to exponential decay over ten days; you can twiddle with it to try and get better results for your site.
For daemon processes.
piddir: directory that daemon processes should write their PID file
(process ID) to. Defaults to /var/run/, which is where this
stuff should usually go on Unix-ish systems.
user: If set, the daemons will try to change their effective user ID
to this user before running. Probably a good idea, especially if
you start the daemons as root. Note: user name, like 'daemon',
group: If set, the daemons will try to change their effective group ID
to this named group. Again, a name, not a numerical ID.
enabled: Whether to enable post-by-email. Defaults to true. You will also need to set up maildaemon.php.
For SMS integration.
enabled: Whether to enable SMS integration. Defaults to true. Queues should also be enabled.
A catch-all for integration with other systems.
taguri: base for tag:// URIs. Defaults to site-server + ',2009'.
For notice inboxes.
enabled: No longer used. If you set this to something other than true, StatusNet will no longer run.
For notice-posting throttles.
enabled: Whether to throttle posting. Defaults to false.
count: Each user can make this many posts in 'timespan' seconds. So, if count
is 100 and timespan is 3600, then there can be only 100 posts
from a user every hour.
timespan: see 'count'.
biolimit: max character length of bio; 0 means no limit; null means to use
the site text limit default.
backup: whether users can backup their own profiles. Defaults to true.
restore: whether users can restore their profiles from backup files. Defaults
delete: whether users can delete their own accounts. Defaults to false.
move: whether users can move their accounts to another server. Defaults
Options with new users.
default: nickname of a user account to automatically subscribe new
users to. Typically this would be system account for e.g.
service updates or announcements. Users are able to unsub
if they want. Default is null; no auto subscribe.
welcome: nickname of a user account that sends welcome messages to new
users. Can be the same as 'default' account, although on
busy servers it may be a good idea to keep that one just for
'urgent' messages. Default is null; no message.
If either of these special user accounts are specified, the users should be created before the configuration is updated.
The software lets users upload files with their notices. You can configure the types of accepted files by mime types and a trio of quota options: per file, per user (total), per user per month.
We suggest the use of the pecl file_info extension to handle mime type detection.
supported: an array of mime types you accept to store and distribute,
like 'image/gif', 'video/mpeg', 'audio/mpeg', etc. Make sure you
setup your server to properly recognize the types you want to
uploads: false to disable uploading files with notices (true by default).
For quotas, be sure you've set the upload_max_filesize and post_max_size in php.ini to be large enough to handle your upload. In httpd.conf (if you're using apache), check that the LimitRequestBody directive isn't set too low (it's optional, so it may not be there at all).
process_links: follow redirects and save all available file information
(mimetype, date, size, oembed, etc.). Defaults to true.
file_quota: maximum size for a single file upload in bytes. A user can send
any amount of notices with attachments as long as each attachment
is smaller than file_quota.
user_quota: total size in bytes a user can store on this server. Each user
can store any number of files as long as their total size does
not exceed the user_quota.
monthly_quota: total size permitted in the current month. This is the total
size in bytes that a user can upload each month.
dir: directory accessible to the Web process where uploads should go.
Defaults to the 'file' subdirectory of the install directory, which
should be writeable by the Web user.
server: server name to use when creating URLs for uploaded files.
Defaults to null, meaning to use the default Web server. Using
a virtual server here can speed up Web performance.
path: URL path, relative to the server, to find files. Defaults to
main path + '/file/'.
ssl: whether to use HTTPS for file URLs. Defaults to null, meaning to
guess based on other SSL settings.
sslserver: if specified, this server will be used when creating HTTPS
URLs. Otherwise, the site SSL server will be used, with /file/ path.
sslpath: if this and the sslserver are specified, this path will be used
when creating HTTPS URLs. Otherwise, the attachments|path value
will be used.
show_thumbs: show thumbnails in notice lists for uploaded images, and photos
and videos linked remotely that provide oEmbed info. Defaults to true.
show_html: show (filtered) text/html attachments (and oEmbed HTML etc.).
Doesn't affect AJAX calls. Defaults to false.
filename_base: for new files, choose one: 'upload', 'hash'. Defaults to hash.
Options for group functionality.
maxaliases: maximum number of aliases a group can have. Default 3. Set
to 0 or less to prevent aliases in a group.
desclimit: maximum number of characters to allow in group descriptions.
null (default) means to use the site-wide text limits. 0
means no limit.
addtag: Whether to add a tag for the group nickname for every group post
(pre-1.0.x behaviour). Defaults to false.
Some stuff for search.
type: type of search. Ignored if PostgreSQL or Sphinx are enabled. Can either be 'fulltext' or 'like' (default). The former is faster and more efficient but requires the lame old MyISAM engine for MySQL. The latter will work with InnoDB but could be miserably slow on large systems. We'll probably add another type sometime in the future, with our own indexing system (maybe like MediaWiki's).
handle: boolean. Whether we should register our own PHP session-handling
code (using the database and cache layers if enabled). Defaults to false.
Setting this to true makes some sense on large or multi-server
sites, but it probably won't hurt for smaller ones, either.
debug: whether to output debugging info for session storage. Can help
with weird session bugs, sometimes. Default false.
Using the "XML-RPC Ping" method initiated by weblogs.com, the site can notify third-party servers of updates.
notify: an array of URLs for ping endpoints. Default is the empty array (no notification).
Configuration options specific to notices.
contentlimit: max length of the plain-text content of a notice.
Default is null, meaning to use the site-wide text limit.
0 means no limit.
defaultscope: default scope for notices. If null, the default
scope depends on site/private. It's 1 if the site is private,
0 otherwise. Set this value to override.
Configuration options specific to messages.
contentlimit: max length of the plain-text content of a message. Default is null, meaning to use the site-wide text limit. 0 means no limit.
Configuration options for the login command.
disabled: whether to enable this command. If enabled, users who send the text 'login' to the site through any channel will receive a link to login to the site automatically in return. Possibly useful for users who primarily use an XMPP or SMS interface and can't be bothered to remember their site password. Note that the security implications of this are pretty serious and have not been thoroughly tested. You should enable it only after you've convinced yourself that it is safe. Default is 'false'.
If an installation has only one user, this can simplify a lot of the interface. It also makes the user's profile the root URL.
enabled (boolean, default true): Whether to run in "single user mode".
nickname (string, default null): nickname of the single user. If no nickname is
specified, the site owner account will be used (if present).
We put out a default robots.txt file to guide the processing of Web crawlers. See http://www.robotstxt.org/ for more information on the format of this file.
crawldelay: if non-empty, this value is provided as the Crawl-Delay:
for the robots.txt file. see https://en.wikipedia.org/wiki/Robots_exclusion_standard#Crawl-delay_directive
for more information. Default is zero, no explicit delay.
disallow: Array of (virtual) directories to disallow. Default is 'main',
'search', 'message', 'settings', 'admin'. Ignored when site
is private, in which case the entire site ('/') is disallowed.
Options for the Twitter-like API.
realm: HTTP Basic Auth realm (see http://tools.ietf.org/html/rfc2617 for details). Some third-party tools like ping.fm want this to be 'Identi.ca API', so set it to that if you want to. default = null, meaning 'something based on the site name'.
We optionally put 'rel="nofollow"' on some links in some pages. The following configuration settings let you fine-tune how or when things are nofollowed. See http://en.wikipedia.org/wiki/Nofollow for more information on what 'nofollow' means.
subscribers: whether to nofollow links to subscribers on the profile
and personal pages. Default is true.
members: links to members on the group page. Default true.
peopletag: links to people listed in the peopletag page. Default true.
external: external links in notices. One of three values: 'sometimes',
'always', 'never'. If 'sometimes', then external links are not
nofollowed on profile, notice, and favorites page. Default is
These are some options for fine-tuning how and when the server will shorten URLs.
shortener: URL shortening service to use by default. Users can override
individually. 'internal' by default.
maxurllength: If an URL is strictly longer than this limit, it will be
shortened. Note that the URL shortener service may return an URL longer than this limit. Defaults to 100. Users can override. If set to 0, all URLs will be shortened.
maxnoticelength: If a notice is strictly longer than this limit, all
URLs in the notice will be shortened. Users can override. -1 means the text limit for notices.
We use a router class for mapping URLs to code. This section controls how that router works.
cache: whether to cache the router in cache layers. Defaults to true, but may be set to false for developers (who might be actively adding pages, so won't want the router cached) or others who see strange behavior. You're unlikely to need this unless developing..
Settings for the HTTP client.
ssl_cafile: location of the CA file for SSL. If not set, won't verify
SSL peers. Default unset.
curl: Use cURL http://curl.haxx.se/ for doing HTTP calls. You must
have the PHP curl extension installed for this to work.
proxy_host: Host to use for proxying HTTP requests. If unset, doesn't
do any HTTP proxy stuff. Default unset.
proxy_port: Port to use to connect to HTTP proxy host. Default null.
