-Provides a convinient way of setting up an CGI environment from a HTTP::Request.
+Provides a convinient way of setting up an CGI enviroment from a HTTP::Request.
=head1 METHODS
-=over 4
-
-=item * new
-
-Constructor, this method takes a hash of parameters. The following parameters are
-valid:
-
-=over 8
-
-=item * request
-
- request => HTTP::Request->new( GET => 'http://www.host.com/' )
-
-=item * stdin
-
-A filehandle to be used as standard input, defaults to a temporary filehandle.
-If C<stdin> is C<undef>, standard input will be left as is.
-
- stdin => IO::File->new_tmpfile
- stdin => IO::String->new
- stdin => $fh
- stdin => undef
-
-=item * stdout
-
-A filehandle to be used as standard output, defaults to a temporary filehandle.
-If C<stdout> is C<undef>, standard output will be left as is.
-
- stdout => IO::File->new_tmpfile
- stdout => IO::String->new
- stdout => $fh
- stdout => undef
+=over 4
-=item * stderr
+=item new ( $request [, key => value ] )
-A filehandle to be used as standard error, defaults to C<undef>. If C<stderr> is
-C<undef>, standard error will be left as is.
+Contructor, first argument must be a instance of HTTP::Request
+followed by optional pairs of environment key and value.
- stderr => IO::File->new_tmpfile
- stderr => IO::String->new
- stderr => $fh
- stderr => undef
+=item enviroment
-=item * environment
+Returns a hashref containing the environment that will be used in setup.
+Changing the hashref after setup has been called will have no effect.
-A C<HASH> of additional environment variables to be used in CGI.
-C<HTTP::Request::AsCGI> doesn't autmatically merge C<%ENV>, it has to be
-explicitly given if that is desired. Environment variables given in this
-C<HASH> isn't overridden by C<HTTP::Request::AsCGI>.
+=item setup
- environment => \%ENV
- environment => { PATH => '/bin:/usr/bin', SERVER_SOFTWARE => 'Apache/1.3' }
+Setups the environment and descriptors.
-Following standard meta-variables (in addition to protocol-specific) is setup:
+=item restore
- AUTH_TYPE
- CONTENT_LENGTH
- CONTENT_TYPE
- GATEWAY_INTERFACE
- PATH_INFO
- SCRIPT_NAME
- SERVER_NAME
- SERVER_PORT
- SERVER_PROTOCOL
- SERVER_SOFTWARE
- REMOTE_ADDR
- REMOTE_HOST
- REMOTE_USER
- REQUEST_METHOD
- QUERY_STRING
+Restores the enviroment and descriptors. Can only be called after setup.
-Following non-standard but common meta-variables is setup:
+=item request
- HTTPS
- REMOTE_PORT
- REQUEST_URI
+Returns the request given to constructor.
-Following meta-variables is B<not> setup but B<must> be provided in CGI:
+=item response
- PATH_TRANSLATED
+Returns a HTTP::Response. Can only be called after restore.
-Following meta-variables is B<not> setup but common in CGI:
+=item stdin
- DOCUMENT_ROOT
- SCRIPT_FILENAME
- SERVER_ROOT
+Accessor for handle that will be used for STDIN, must be a real seekable
+handle with an file descriptor. Defaults to a tempoary IO::File instance.
-=item * dup
+=item stdout
-Boolean to indicate whether to C<dup> standard filehandle or to assign the
-typeglob representing the standard filehandle. Defaults to C<true>.
+Accessor for handle that will be used for STDOUT, must be a real seekable
+handle with an file descriptor. Defaults to a tempoary IO::File instance.
- dup => 0
- dup => 1
+=item stderr
-=item * restore
-
