Disable Browser Caching

To (try) and prevent browser/proxy caching, add the following HTTP Headers:



Expires: -1

Cache-Control: no-transform, no-cache, no-store, max-age=0, must-revalidate

Expires: Mon, 26 Jul 1997 05:00:00 GMT

Pragma: no-cache

Keep-Alive: timeout=3, max=993

This should prevent browsers caching information. As an aside, it may also prevent the Open Wave Open Web mobile web trans-f**ker re-writing the user-agent that you get sent, so that you get the _real_ user-agent, instead of Mozilla/5.0 (compatible; OpenWeb 5.7.1-03) Opera 8.54.
