HTML::Mason::ApacheHandler - phpMan

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 publicly 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.
