How to test if mod_gzip is working

[Sam Snow]

I have heard of two ways of testing if mod_gzip is working on your web server:

1. Turn "mod_gzip_keep_workfiles     Yes" and then look at the "mod_gzip_temp_dir" and see if files are created. Be sure to change "mod_gzip_keep_workfiles" back to no once you have completed testing.

2. Use the web-based tester at http://leknor.com/code/gziped.php .

Does anyone have any other methods?

i found this code somewhere, added some changes and here it is
very simple ...

#!/usr/bin/perl
use Socket;

if(@ARGV ne 1) {
    print "\nUsage: mod_gzip_test http://your_site.com/yourpage.html\n\n";
        exit;
        }

        $ARGV[0] =~ /http:\/\/(.*)\/(.*)/i;

        $in_addr = (gethostbyname($1))[4];
        $port = 80;
        $addr = sockaddr_in($port, $in_addr);
        $proto = getprotobyname('tcp');

        socket(S, AF_INET, SOCK_STREAM, $proto) or die;
        connect(S, $addr) or die;
        select(S); $| = 1; select(STDOUT);

        print S "GET /$2 HTTP/1.1\nHost: $1\nAccept-Encoding: gzip\nUser-Agent: mod_gzip_test\n\n";

        while(<S>) {
            if(length($_) < 3) { print "$1\n $2\n No compression used.\n"; exit; }
                if(/Content-Encoding: gzip/i) {
                        print ("Page was sent GZIP compressed.\n"); exit;
                            }
                            }

you can also check http://yoursite/mod_gzip_status/

this may vary deppending on your mod_gzip settings.

curl --compressed -v -o/dev/null http://your.domain.tld/some/page

then look for "Content-Encoding: gzip"

Do not use the --head option as HEAD requests will not be compressed.
