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.
