.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The WWW::Mechanize::GZip module tries to fetch a \s-1URL\s0 by requesting
gzip-compression from the webserver.
.PP
If the response contains a header with 'Content\-Encoding: gzip', it
decompresses the response in order to get the original (uncompressed) content.
.PP
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.
.PP
This modules is a direct subclass of WWW::Mechanize and will therefore support
any methods provided by WWW::Mechanize.
.PP
The decompression is handled by Compress::Zlib::memGunzip.
.PP
There is a small webform, you can instantly test, whether a webserver supports
gzip-compression on a particular \s-1URL:\s0

.SS "\s-1METHODS\s0"
.IX Subsection "METHODS"
.IP "prepare_request" 2
.IX Item "prepare_request"
Adds 'Accept\-Encoding' => 'gzip' to outgoing HTTP-headers before sending.
.IP "send_request" 2
.IX Item "send_request"
Unzips response-body if 'content\-encoding' is 'gzip' and
corrects 'content\-length' to unzipped content-length.
