request headers (and bodies) are cached too: where?

[geekpie]

private (browser) caches such as IE6's store requests (headers, or for POST requests, headers and the POST data as the body) as well as responses.

Is it possible to see these somewhere on your machine, or are they only stored in volatile memory (because they're not needed beyond the session)?

Wish I knew more about this topic and could give you a definitive answer. As it stands, you've set me off on some research that now has my head spinning. Here's one resource I found that seems to get into the topic. If you click through to the full page, you'll see that it includes some discussion from a Microsoft engineer.

Please let me know if this information helps.

The Bad

None of them [those browsers tested] will cache POST responses for use with future GETs; this isn’t too surprising, as it’s a little-understood features of the HTTP caching model, but it would be nice to have.

Thanks tedster. the www.mnot.net articles are ones I read regularly but sometimes they raise a lot of questions.

However of great interest was that someone else pointed me to about:cache in Firefox which breaks down cache into volatile and non-volatile.
