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:

   "error_fname"
       Get/set the "ErrorLog" file value (e.g. logs/error_log)

	 $error_fname	   = $s->error_fname();
	 $prev_error_fname = $s->error_fname($new_error_fname);

       obj: $s ( "Apache2::ServerRec object" )
       opt arg1: $new_error_fname ( string )
	   If passed, sets the new value for "ErrorLog"

	   Note the limited functionality under threaded MPMs.

       ret: $error_fname ( string )
	   Returns the "ErrorLog" value setting.

	   If $new_error_fname is passed returns the setting before the
	   change.

       since: 2.0.00

   "is_virtual"
       Test whether $s is a virtual host object

	 $is_virtual = $s->is_virtual();

       obj: $s ( "Apache2::ServerRec object" )
       ret: $is_virtual ( boolean )
	   Returns the is_virtual setting.

	   If $new_is_virtual is passed, returns the setting before the
	   change.

       since: 2.0.00

       Example:

	 print "This is a virtual host" if $s->is_virtual();

   "keep_alive"
       Get/set the "KeepAlive" setting, which specifies whether Apache should
       accept more than one request over the same connection from the same
       client.

	 $keep_alive	  = $s->keep_alive();
	 $prev_keep_alive = $s->keep_alive($new_keep_alive);

	   change.

       since: 2.0.00

   "keep_alive_timeout"
       Get/set the "KeepAliveTimeout" setting (in microsecs), which specifies
       how long Apache will wait for another request before breaking a
       "KeepAlive" connection.

	 $prev_keep_alive_timeout = $s->keep_alive_timeout($new_timeout);

       obj: $s ( "Apache2::ServerRec object" )
       opt arg1: $new_keep_alive_timeout ( integer )
	   The expected value is in microsecs.

	   If passed, sets the new "KeepAlive" timeout.

	   Note the limited functionality under threaded MPMs.

       ret: $keep_alive_timeout ( integer )

       vhosts:

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

	   If $new_timeout is passed, returns the setting before the change.

       since: 2.0.00

       Let us repeat again: the timeout values is microseconds. For example to
       set the timeout to 20 secs:

	 $s->timeout(20_000_000);

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);

       obj: $s ( "Apache2::ServerRec object" )
       opt arg1: $new_names ( "APR::ArrayHeader" )
	   If passed, sets the new names.

	   Note the limited functionality under threaded MPMs.

       ret: $names ( "APR::ArrayHeader" )
	   Returns the names setting.

	   If $new_names is passed, returns the setting before the change.

       since: 2.0.00

       META: we don't have "APR::ArrayHeader" yet

   "wild_names"
       Wildcarded names for ServerAlias servers

	 $wild_names	  = $s->wild_names();
	 $prev_wild_names = $s->wild_names($new_wild_names);

       obj: $s ( "Apache2::ServerRec object" )
       opt arg1: $new_wild_names ( "APR::ArrayHeader" )
	   If passed, sets the new wild_names.

	   Note the limited functionality under threaded MPMs.

       ret: $wild_names ( "APR::ArrayHeader" )
