=head1 NAME

XML::Compile::SOAP::Daemon::CGI - CGI based server

=head1 INHERITANCE

 XML::Compile::SOAP::Daemon::CGI
   is a XML::Compile::SOAP::Daemon

=head1 SYNOPSIS

 #### have a look in the examples directory!
 use XML::Compile::SOAP::Daemon::CGI;
 my $daemon = XML::Compile::SOAP::Daemon::CGI->new;

 # initialize definitions from WSDL
 my $wsdl    = XML::Compile::WSDL11->new(...);
 $wsdl->importDefinitions(...); # more schemas
 $daemon->operationsFromWSDL($wsdl, callbacks => ...);

 # per connected client
 my $query = CGI->new;
 $daemon->runCgiRequest(query => $query);

=head1 DESCRIPTION

This module handles the exchange of SOAP messages via Apache, using
mod_perl and the popular Perl module CGI.  Have a look at the
F<examples/> directory, contained in the C<XML-Compile-SOAP-Daemon>
distribution.

This abstraction level of the object (code in this pm file) is not
concerned with parsing or composing XML, but only worries about the
HTTP transport specifics of SOAP messages.

=over 4

=item $obj-E<gt>B<process>(OPTIONS)

Process the content of a single message. Not to be called directly.

=item $obj-E<gt>B<run>(OPTIONS)

Used by L<runCgiRequest()|XML::Compile::SOAP::Daemon::CGI/"Running the server"> to process a connection. Not to be called
directly.

=item $obj-E<gt>B<runCgiRequest>(OPTIONS)

 -Option     --Default
  postprocess  undef
  query        <created internally>

=over 2

=item postprocess => CODE

When defined, the CODE will get called with a HASH (containing OPTIONS
and other compile information), a HASH of headers (which you may change),
the HTTP return code, and a reference to the message body (which may be
changed as well).

Be warned that the message body must be considered as bytes, so not
as Latin1 or utf-8 string.  You may wish to add or remove bytes. The
Content-Length will be added to the headers after the call.

=head2 How to use the CGI module

The code and documentation for this module was contributed by Patrick
Powell in December 2010. Both have seen major changes since.

Go to the F<examples/mod_perl/> directory which is included in
the distribution of this module, L<XML::Compile::SOAP::Daemon|XML::Compile::SOAP::Daemon>.
There you find a README describing the process.
