use Apache2::ServerRec ();
use Apache2::ServerUtil ();
my $server = Apache2::ServerUtil->server;
my $vhosts = 0;

$new_timeout ( integer )
If passed, sets the new timeout (the value should be in microseconds).
$timeout ( integer )
Returns the timeout setting in microseconds.
If $new_timeout is passed, returns the setting before the change.
Let us repeat again: the timeout values is microseconds. For example to set the timeout to 20 secs:
$s->timeout(20_000_000);
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|docs::2.0::user::handlers::server/C_PerlChildInitHandler_>).
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.
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.
addrsGet the addrs value
$addrs = $s->addrs();
$s
( Apache2::ServerRec object|docs::2.0::api::Apache2::ServerRec )
$addrs
( Apache2::ServerAddr|docs::2.0::api::Apache2::ServerAddr )
Returns the addrs setting.
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_defaultsGet the lookup_defaults value. MIME type info, etc., before we start checking per-directory info.
$lookup_defaults = $s->lookup_defaults();
$s
( Apache2::ServerRec object|docs::2.0::api::Apache2::ServerRec )
$lookup_defaults

Returns the lookup_defaults setting.
