What would I need to add to ubb_status.cgi, poll_ssi.cgi, ubb_hits.cgi, ubb_checkmsg.cgi in order for them to get the same benefit?
Does this work for PHP and/or Javascript like the Newsfader?

If you write your own code I have a suggestion; use only a single print for output. This way, you do not need any 3rd party buffering module like this and it'll be easy to port to platforms like mod_perl. Originally posted by AllenAyres:

I'm seeing 65kb (66009 bytes) in IE and 6.7kb in firefox on the xbox site.
[/qb] There are several alternatives in CPAN, which basicaly do the same thing: buffer STDOUT, split body and headers and gzip body. And they may be better than this "cgi_buffer" -- I don't like the coding. But this one ( http://search.cpan.org/dist/CGI-WebGzip/ ) gives a nice idea to display the compressed size If you send a cookie only for this operation, you can even display compression ratio. For eaxample this will probably do the trick: if ($cgi_buffer::compress_content) {
foreach $encoding ('x-gzip', 'gzip') {
$_ = lc($ENV{'HTTP_ACCEPT_ENCODING'});
if ( m/$encoding/i && lc($content_type[0]) eq 'text') {
my $size_normal = length($body);
$body = Compress::Zlib::memGzip($body);
my $size_gzip = length($body);
my $ubb_gzipr = sprintf("%.2f",100-($size_gzip * 100 / $size_normal));
push @o, "Content-Encoding: $encoding";
push @o, "Vary: Accept-Encoding";
push @o, "Set-Cookie: UBBGZIPRATIO=$ubb_gzipr; path=/";
last;
}
}
}You can then use a javascript function to read "UBBGZIPRATIO" cookie: <script>document.write("Page compression ratio: "+read_cookie('UBBGZIPRATIO'))</script>

If you can write a better version of this mod, please do. I only ported this from the old version, and wouldn't be suprised if I did that poorly.

And the old one is based on a module 4+ years old

No, I can't write a better version since the concept is the same and a little further can be done. But there are better alternatives like CGI::WebGzip. It auto-checks the existence of Compress::Zlib and does not require any other module like "IO::String" or MD5 Also there is this one: http://search.cpan.org/dist/CGI-Compress-Gzip but it requires IO::Zlib There may be some other modules...
