DESCRIPTION

CGI::Compress::Gzip extends the CGI infrastructure to compresses
output, whenever possible.  It uses IO::Zlib (a filehandle wrapper
around the C zlib library).  If this is missing, the functionality
degrades gracefully to the typical CGI behavior.  The programmer can
selectively enable or disable the compression functionality at will.
This module does not rely on any particular server setup.  It should
work anywhere that CGI.pm works.

Apache mod_perl users may prefer the more straightforward
implementation offered by the Apache::Compress or Apache::GzipChain
modules, although those offer less control to the programmer.

WARNING: as of v0.15 this module is working on Linux and MacOSX
but broken on Windows and Solaris (debugging help would be greatly
appreciated on these platforms).  Specifically, I've tested that it
runs well on the following:

                  RedHat_7.3  MacOSX_10.2.6
      perl 5.6.0                   ok          (Apple's perl)
      perl 5.6.1      ok
      perl 5.8.0                   ok
  mod_perl 5.6.0                   ok          (Apple's mod_perl and Apache 1.3.27)
  mod_perl 5.6.1      ok                       (Apache 1.3.27)


KNOWN ISSUES

* This module fails tests specifically under Windows in ways I do not
  understand, as reported by CPANPLUS testers.  There is some problem
  with my IO::Zlib tests.  If anyone knows about IO::Zlib failures or
  caveats on Windows, please let me know.  It *might* be related to
  binmode, but I have not tested this theory.

* This module has been observed to fail on Solaris.  The error is very
  strange and may be Compress::Zlib's fault.  In a nutshell,
  Compress::Zlib gets into infinite recursion in its AUTOLOAD
  function.  I don't know the cause yet...
