WWW::Mechanize::GZip(3pm)				User Contributed Perl Documentation				 WWW::Mechanize::GZip(3pm)

NAME

       WWW::Mechanize::GZip - tries to fetch webpages with gzip-compression

VERSION

       Version 0.10

SYNOPSIS

	   use WWW::Mechanize::GZip;

	   my $mech = WWW::Mechanize::GZip->new();
	   my $response = $mech->get( $url );

	   print "x-content-length (before unzip) = ", $response->header('x-content-length');
	   print "content-length (after unzip) = ", $response->header('content-length');

DESCRIPTION

       The WWW::Mechanize::GZip module tries to fetch a URL by requesting gzip-compression from the webserver.

       If the response contains a header with 'Content-Encoding: gzip', it decompresses the response in order to get the original (uncompressed)
       content.

       This module will help to reduce bandwith fetching webpages, if supported by the webeserver. If the webserver does not support gzip-
       compression, no decompression will be made.

       This modules is a direct subclass of WWW::Mechanize and will therefore support any methods provided by WWW::Mechanize.

       The decompression is handled by Compress::Zlib::memGunzip.

       There is a small webform, you can instantly test, whether a webserver supports gzip-compression on a particular URL:
       <http://www.computerhandlung.de/www-mechanize-gzip.htm>

   METHODS
       prepare_request
	 Adds 'Accept-Encoding' => 'gzip' to outgoing HTTP-headers before sending.

       send_request
	 Unzips response-body if 'content-encoding' is 'gzip' and corrects 'content-length' to unzipped content-length.
