Following a previous post about HTTP 1.1 caching mechanisms, I have been asked whether common browsers were actually compliant or not, so I wrote a little test to verify if at least basic features were supported.

The results for your browser will appear in the frame below.

Update: This is a new version with cache headers completely handled by PHP instead of using apache mod_expires. I had to do this because I could’nt deactivate chunk transfer encoding of pages generated by php on my host, and this prevents HTTP 1.1 caching headers to be inserted by apache … the test seems to work now, but it is still in beta
