Typically you'd use the "Expires" header with a negative time value, meaning a date string that's at least 1 second in the past.
But "Cache-Control:" or "Pragma:" with a max-age=0, no-store or a no-cache directive should prevent any storing in a cache either, else it's not conform to the RFC. But it's true that there are still many caches ignoring those. -----Original Message----- From: Leandro Scott R.Z. Jacques [mailto:[EMAIL PROTECTED] Sent: Mittwoch, 9.

I need to know if there is a HTTP header that prevents the proxy cache to cache an object in any way. I've been reading and I noticed that pragma: no-cache doesn't prevent the cache to store an object, it only tells the cache to validate the object everytime it's requested by a client.
