Configuration:
- PerlHandler My
+ PerlHandler MyClass
or
- PerlHandler My->handler
+ PerlHandler MyClass->handler
Since the handler is invoked as a method, it may inherit from other
classes:
- PerlHandler My->method
+ PerlHandler MyClass->method
+
+In this case, the C<MyClass> class inherits this method from
+C<BaseClass>. This means that any method of C<MyClass> or any of its
+parent classes can serve as a mod_perl handler, and that you can apply
+good OO methodology within your mod_perl handlers.
+
+For instance, you could have this base class:
+
+ package ServeContent;
+
+ use Apache::Constants qw(OK);
+
+ sub handler($$) {
+ my($class, $r) = @_;
+
+ $r->send_http_header('text/plain');
+ $r->print($class->get_content());
+
+ return OK;
+ }
+
+ sub get_content {
+ return 'Hello World';
+ }
+
+ 1;
+
+And then use the same base class for different contents:
-META: requires more explanation!
+ package HelloWorld;
+
+ use ServeContent;
+ @ISA = qw(ServeContent);
+
+ sub get_content {
+ return 'Hello, happy world!';
+ }
+
+ package GoodbyeWorld;
+
+ use ServeContent;
+ @ISA = qw(ServeContent);
+
+ sub get_content {
+ return 'Goodbye, cruel world!';
+ }
+
+ 1;
+
+Now you can keep the same handler subroutine for a group of modules
+which are similiar. The following configuration will enable the
+handlers from the subclasses:
-In this case, the C<My> class inherits this method from C<BaseClass>.
+ <Location /hello>
+ SetHandler perl-script
+ PerlHandler HelloWorld->handler
+ </Location>
+
+ <Location /bye>
+ SetHandler perl-script
+ PerlHandler GoodbyeWorld->handler

+Overview of some of the most popular modules for mod_perl, both to use
+directly from your code and as mod_perl handlers.
+
+Over the time, mod_perl has collected an impressive amount of modules
+which are distributed in the standard Perl way, over CPAN. Found in
+the C<Apache::> namespace, these implement various functionalities you
+might need when creating a mod_perl-based website. For mod_perl, we
+can actually make a distinction between two types of modules:
+
+=over
+
+=item *
+
+Apache handlers, which handle request phases or whole requests and are
+standalone (C<Apache::GTopLimit> for example).
+
+=item *
+
+Convenience modules, which are like standard Perl modules,
+implementing some useful aspect of web programming, usually using
+mod_perl API for a greater performance or functionality unavailable in
+plain Perl. (A good example of this is C<Apache::Session>.) These
+modules exist under the C<Apache::> namespace because they can only be
+used under mod_perl.
+
+=back
+
+For a complete list of modules, see the L<Apache/Perl Module
+list|products::apache-modlist>.

=head1 Apache::Filter - Alter the output of previous handlers
-META: to be written (actually summarized the info from Apache::Filter
-manpage)
+C<Apache::Filter>, like C<Apache::OutputChain>, allows you to chain
+stacked handlers. It's not very different from C<Apache::OutputChain>,
+except for the way you configure the filters. A normal configuration
+with C<Apache::Filter> would be the following:
+
+ PerlModule Apache::Filter Apache::RegistryFilter Apache::SSI Apache::Gzip
+ Alias /perl /home/httpd/perl
+ <Location /perl>
+ SetHandler "perl-script"
+ Options +ExecCGI
+ PerlSetVar Filter On
+ PerlHandler Apache::RegistryFilter Apache::SSI Apache::Gzip
+ </Location>
+
+This accomplishes some things many CGI programmers want: you can
+output SSI code from your C<Apache::Registry> scripts, have it parsed
+by C<Apache::SSI>, and then compressed with C<Apache::Gzip> (see
+L<Apache::Gzip|guide::modules/Apache__Gzip___Auto_compress_web_files_with_Gzip>
+below).
+
+Thanks to C<Apache::Filter>, you can also write your own filter
+modules, which allow you to read in the output from the previous
+handler in the chain and modify it. You would do something like this
+in your C<handler> subroutine:
+
+ $r = $r->filter_register(); # Required
+ my $fh = $r->filter_input(); # Optional (you might not need the input FH)
+ while (<$fh>) {
+ s/ something / something else /;
+ print;
+ }
+
+Another interesting thing to do with C<Apache::Filter> would be to use
+it for XML output from your scripts(these modules are hypothetical,
+this is handled much better by AxKit, Matt Seargeant's XML application
+server for mod_perl (see http://www.axkit.org/ ).
+
+ <Location /perl/xml-output>
+ SetHandler perl-script
+ Options +ExecCGI
+ PerlSetVar Filter On
+ PerlHandler Apache::RegistryFilter Apache::XSLT
+ </Location>
+
+As you can see, you can get a lot of freedom by using stacked
+handlers, allowing you to separate various parts of your programs and
+leave those tasks up to other modules, which may already be available
+from CPAN (this is much better than the CGI time when your script
+would have to do I<everything> itself, because you couldn't do much
+with its output).
