NAME

       Apache::ServerUtil -- Methods for work with Apache::Server object

SYNOPSIS

	 use Apache::ServerUtil;

	 $s = Apache->server;
	 my $srv_cfg = $s->dir_config;

	 # get 'conf/' dir path using $r
	 my $conf_dir = Apache::server_root_relative('conf', $r->pool);

	 # get 'log/' dir path using default server startup pool
	 my $log_dir = Apache::server_root_relative('log');

DESCRIPTION

       "Apache::ServerUtil" provides the Perl API for Apache server object.

       META: complete

API

       Function arguments (if any) and return values are shown in the function's synopsis.

       CONSTANTS

       o server_root
	   returns the value set by the "ServerRoot" directive.

       FUNCTIONS

       o server_root_relative()
	   Returns the canonical form of the filename made absolute to "ServerRoot":

	     Apache::server_root_relative($pool, $fname);

	   $fname is appended to the value of "ServerRoot" and return it. e.g.:

	     my $log_dir = Apache::server_root_relative($r->pool, 'logs');

	   If $fname is not specified, the value of "ServerRoot" is returned with a trailing "/". (it's the same as using '' as $fname's value).

	   Also see the "server_root" constant.

       METHODS

       o server()
	   The main server's object can be retrieved with:

	     $s = Apache->server;

	   Gets the "Apache::Server" object for the main server.

       o dir_config()
	   dir_config() provides an interface for the per-server variables specified by the "PerlSetVar" and "PerlAddVar" directives, and also can
	   be manipulated via the "APR::Table" methods.

	   The keys are case-insensitive.

	     $t = $s->dir_config();

	   dir_config() called in a scalar context without the $key argument returns a HASH reference blessed into the APR::Table class. This
	   object can be manipulated via the APR::Table methods. For available methods see APR::Table.

	     @values = $s->dir_config($key);

	   If the $key argument is passed in the list context a list of all matching values will be returned. This method is ineffective for big
	   tables, as it does a linear search of the table. Thefore avoid using this way of calling dir_config() unless you know that there could
	   be more than one value for the wanted key and all the values are wanted.

	     $value = $s->dir_config($key);

	   If the $key argument is passed in the scalar context only a single value will be returned. Since the table preserves the insertion
	   order, if there is more than one value for the same key, the oldest value assosiated with the desired key is returned. Calling in the
	   scalar context is also much faster, as it'll stop searching the table as soon as the first match happens.

	     $s->dir_config($key => $val);

	   If the $key and the $val arguments are used, the set() operation will happen: all existing values associated with the key $key (and the
	   key itself) will be deleted and $value will be placed instead.

	     $s->dir_config($key => undef);

	   If $val is undef the unset() operation will happen: all existing values associated with the key $key (and the key itself) will be
	   deleted.

       o add_handlers()
       o get_handlers()
