19 The ApacheHandler object links Mason to mod_perl (version 1 or 2),
20 running components in response to HTTP requests. It is controlled
21 primarily through parameters to the new() constructor.
22
24 apache_status_title
25 Title that you want this ApacheHandler to appear as under
26 Apache::Status. Default is "HTML::Mason status". This is useful
27 if you create more than one ApacheHandler object and want them all
28 visible via Apache::Status.
29 args_method
31 Method to use for unpacking GET and POST arguments. The valid
32 options are 'CGI' and 'mod_perl'; these indicate that a "CGI.pm" or
33 "Apache::Request" object (respectively) will be created for the
34 purposes of argument handling.
35 'mod_perl' is the default under mod_perl-1 and requires that you
37 have installed the "Apache::Request" package. Under mod_perl-2,
38 the default is 'CGI' because "Apache2::Request" is still in
39 development.
40 If args_method is 'mod_perl', the $r global is upgraded to an
42 Apache::Request object. This object inherits all Apache methods and
43 adds a few of its own, dealing with parameters and file uploads.
44 See "Apache::Request" for more information.
45 If the args_method is 'CGI', the Mason request object ($m) will
47 have a method called "cgi_object" available. This method returns
48 the CGI object used for argument processing.
49 While Mason will load "Apache::Request" or "CGI" as needed at
51 runtime, it is recommended that you preload the relevant module
52 either in your httpd.conf or handler.pl file, as this will save
53 some memory.
54 decline_dirs
56 True or false, default is true. Indicates whether Mason should
57 decline directory requests, leaving Apache to serve up a directory
58 index or a "FORBIDDEN" error as appropriate. See the allowing
59 directory requests section of the administrator's manual for more
60 information about handling directories with Mason.
61 interp
63 The interpreter object to associate with this compiler. By default
64 a new object of the specified interp_class will be created.
65 interp_class
67 The class to use when creating a interpreter. Defaults to
68 HTML::Mason::Interp.
69
71 All of the above properties, except interp_class, have standard
72 accessor methods of the same name: no arguments retrieves the value,
73 and one argument sets it, except for args_method, which is not
74 settable. For example:
75 my $ah = HTML::Mason::ApacheHandler->new;
77 my $decline_dirs = $ah->decline_dirs;
78 $ah->decline_dirs(1);
79
81 The ApacheHandler object has a few other publicly accessible methods
82 that may be of interest to end users.
83 handle_request ($r)
85 This method takes an Apache or Apache::Request object representing
86 a request and translates that request into a form Mason can
87 understand. Its return value is an Apache status code.
88 Passing an Apache::Request object is useful if you want to set
90 Apache::Request parameters, such as POST_MAX or DISABLE_UPLOADS.
91 prepare_request ($r)
93 This method takes an Apache object representing a request and
94 returns a new Mason request object or an Apache status code. If it
95 is a request object you can manipulate that object as you like, and
96 then call the request object's "exec" method to have it generate
97 output.
98 If this method returns an Apache status code, that means that it
100 could not create a Mason request object.
101 This method is useful if you would like to have a chance to decline
103 a request based on properties of the Mason request object or a
104 component object. For example:
105 my $req = $ah->prepare_request($r);
107 # $req must be an Apache status code if it's not an object
108 return $req unless ref($req);
109 return DECLINED
111 unless $req->request_comp->source_file =~ /\.html$/;
112 $req->exec;
114 request_args ($r)
116 Given an Apache request object, this method returns a three item
117 list. The first item is a hash reference containing the arguments
118 passed by the client's request.
119 The second is an Apache request object. This is returned for
121 backwards compatibility from when this method was responsible for
122 turning a plain Apache object into an Apache::Request object.
123 The third item may be a CGI.pm object or "undef", depending on the
125 value of the args_method parameter.
