How to test if mod_cache works

Some information:

"Cache-Control: must-revalidate, max-age=300"

This tells mod_cache to cache the page for 300 seconds (max-age) - unfortunately mod_cache doesn't know the s-maxage option (see http://www.mnot.net/cache_docs/#CACHE-CONTROL), that's why we must use the max-age option (which also tells your browser to cache).

If mod_cache knew the s-maxage option, we could use

"Cache-Control: must-revalidate, max-age=0, s-maxage=300"

which would tell mod_cache, but not the browser, to cache the page.

The question: How do I know if mod_cache is actually memory caching anything at all.

200 responses will contain an Age header. At least it does on Apache 2.2. I did not see the header on 304 responses.

With firebug, you can disable the entire cache, so every css, js, image, video ...etc, it will request to the web server.

So if this mod_cache is working, activate the firebug cache and the files that have that header, only will be requested to the web server every s-maxage time
