NAME

       HTML::Mason::ApacheHandler - Mason/mod_perl interface

SYNOPSIS

	   use HTML::Mason::ApacheHandler;

	   my $ah = HTML::Mason::ApacheHandler->new (..name/value params..);
	   ...
	   sub handler {
	       my $r = shift;
	       $ah->handle_request($r);
	   }

DESCRIPTION

       The ApacheHandler object links Mason to mod_perl (version 1 or 2), running components in response to HTTP requests. It is controlled
       primarily through parameters to the new() constructor.

PARAMETERS TO THE new() CONSTRUCTOR
       apache_status_title
	   Title that you want this ApacheHandler to appear as under Apache::Status.  Default is "HTML::Mason status".	This is useful if you
	   create more than one ApacheHandler object and want them all visible via Apache::Status.

       args_method
	   Method to use for unpacking GET and POST arguments. The valid options are 'CGI' and 'mod_perl'; these indicate that a "CGI.pm" or
	   "Apache::Request" object (respectively) will be created for the purposes of argument handling.

	   'mod_perl' is the default under mod_perl-1 and requires that you have installed the "Apache::Request" package.  Under mod_perl-2, the
	   default is 'CGI' because "Apache2::Request" is still in development.

	   If args_method is 'mod_perl', the $r global is upgraded to an Apache::Request object. This object inherits all Apache methods and adds
	   a few of its own, dealing with parameters and file uploads.	See "Apache::Request" for more information.

	   If the args_method is 'CGI', the Mason request object ($m) will have a method called "cgi_object" available.  This method returns the
	   CGI object used for argument processing.

	   While Mason will load "Apache::Request" or "CGI" as needed at runtime, it is recommended that you preload the relevant module either in
	   your httpd.conf or handler.pl file, as this will save some memory.

       decline_dirs
	   True or false, default is true. Indicates whether Mason should decline directory requests, leaving Apache to serve up a directory index
	   or a "FORBIDDEN" error as appropriate. See the allowing directory requests section of the administrator's manual for more information
	   about handling directories with Mason.

       interp
	   The interpreter object to associate with this compiler. By default a new object of the specified interp_class will be created.

       interp_class
	   The class to use when creating a interpreter. Defaults to HTML::Mason::Interp.

ACCESSOR METHODS

       All of the above properties, except interp_class, have standard accessor methods of the same name: no arguments retrieves the value, and
       one argument sets it, except for args_method, which is not settable.  For example:

	   my $ah = HTML::Mason::ApacheHandler->new;
	   my $decline_dirs = $ah->decline_dirs;
	   $ah->decline_dirs(1);

OTHER METHODS

       The ApacheHandler object has a few other publically accessible methods that may be of interest to end users.

       handle_request ($r)
	   This method takes an Apache or Apache::Request object representing a request and translates that request into a form Mason can
	   understand.	Its return value is an Apache status code.

	   Passing an Apache::Request object is useful if you want to set Apache::Request parameters, such as POST_MAX or DISABLE_UPLOADS.

       prepare_request ($r)
	   This method takes an Apache object representing a request and returns a new Mason request object or an Apache status code.  If it is a
	   request object you can manipulate that object as you like, and then call the request object's "exec" method to have it generate output.

	   If this method returns an Apache status code, that means that it could not create a Mason request object.

	   This method is useful if you would like to have a chance to decline a request based on properties of the Mason request object or a
	   component object.  For example:

	       my $req = $ah->prepare_request($r);
	       # $req must be an Apache status code if it's not an object
	       return $req unless ref($req);

	       return DECLINED
		   unless $req->request_comp->source_file =~ /.html$/;

	       $req->exec;

       request_args ($r)
	   Given an Apache request object, this method returns a three item list.  The first item is a hash reference containing the arguments
	   passed by the client's request.

	   The second is an Apache request object.  This is returned for backwards compatibility from when this method was responsible for turning
	   a plain Apache object into an Apache::Request object.

	   The third item may be a CGI.pm object or "undef", depending on the value of the args_method parameter.
