Description
Apache2::ServerRec provides the Perl API for Apache server_rec object.
Apache2::ServerUtil provides an extra functionality.
API
Apache2::ServerRec provides the following functions and/or methods:

Notes
Limited Functionality under Threaded MPMs
Note that under threaded MPMs, some of the read/write accessors, will be able to set values only before threads are spawned (i.e. before the ChildInit phase). Therefore if you are developing your application on the non-threaded MPM, but planning to have it run under threaded mpm, you should not use those methods to set values after the ChildInit phase.
The affected accessor methods are marked as such in their respective documentation entries.
Unsupported API
Apache2::ServerRec also provides auto-generated Perl interface for a few other methods which aren't tested at the moment and therefore their API is a subject to change. These methods will be finalized later as a need arises. If you want to rely on any of the following methods please contact the the mod_perl development mailing list so we can help each other take the steps necessary to shift the method to an officially supported API.
addrs
Get the addrs value
$addrs = $s->addrs();
- obj:
$s(Apache2::ServerRec object) - ret:
$addrs(Apache2::ServerAddr) -
Returns the addrs setting.
- since: subject to change
META: this methods returns a vhost-specific Apache2::ServerAddr object, which is not implemented at the moment. See the struct server_addr_rec entry in httpd-2.0/include/httpd.h for more information. It seems that most (all?) of the information in that record is available through other APIs.
lookup_defaults
Get the lookup_defaults value. MIME type info, etc., before we start checking per-directory info.
$lookup_defaults = $s->lookup_defaults();
- obj:
$s(Apache2::ServerRec object) - ret:
$lookup_defaults(Apache2::ConfVector) -
Returns the lookup_defaults setting.
- since: subject to change
module_config
Get config vector containing pointers to modules' per-server config structures.
$module_config = $s->module_config();
- obj:
$s(Apache2::ServerRec object) - ret:
$module_config(Apache2::ConfVector) -
Returns the module_config setting.
- since: subject to change
names
Get/set the value(s) for the ServerAlias setting
$names = $s->names();
$prev_names = $s->names($new_names);

If passed, sets the new names.
- ret:

If
$new_namesis passed, returns the setting before the change. - since: 2.0.00
