RE: Cache control HTTP headers

 
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.

Subject: Cache control HTTP headers

I know that there are many HTTP headers that are used
to control how the cache has to behave with a given
object. 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.
