Test if mod_gzip/mod_deflate is enabled from whatsmyip.org

While working on a project on mod_deflate, I have stumbled across this great link that allows you to test remotely any server if it has enabled compression (mod_gzip/mod_deflate) and also see some statistics on the bandwidth saved on the particular URL tested (this is achieved by making one request without gzip enabled and another one with gzip enabled).
I found it very handy while testing various things…

http://www.whatsmyip.org/http_compression/

http://www.ducea.com is gzipped

Original Size: 43 K
Gzipped Size: 10 K

Thanks for this, configuring Apache to get either mod_deflate or mod_gzip working looks tricky but this confirmation of whether I have got it working or not will help a little, thanks for posting this

This is great because even if you have mod_deflate loaded, the test page will still report “not gzipped” if you don’t tell apache which file types to deflate.

I have a cgi script, that the link does not work on. Any reason?

Nevermind, it’s because it wasn’t following the redirect.

If you have an internal page or a page that you cannot test on this, install firebug in firefox and enable the Net console in it. (Right click a page and click Inspect Element once you have Firebug installed to activate it.)

This is a very helpful link for checking gzip compression, thanks!

curl could accomplish the same thing
curl http://example.com -H “Accept-Encoding: gzip,deflate”

Awesome! I found this on google while trying to learn how to test if a page is served compressed.

Thanks for the link. I have php installed as Cgi. So I could not use apache_get_modules() on it as it does not work with cgi php to know about mod_deflate. Your resource come handy here.
