mod_proxy overwrites Date header





------- Additional Comments From [EMAIL PROTECTED]  2003-01-15 19:59 -------
Having both Cache-Control: no-cache and Expires is
perfectly valid/legal. "no-cache" does not mean "do not
cache/store"; it means "revalidate on every request". Expires
refers to content freshness which is often a separate issue.

Some applications may be able to predict expiration times and may still
want to see all [validation] requests. Some caches
(think CDNs like Akamai or bookmark revalidation services) may use the 
combination to optimize their [caching] decisions.

Cache-control overrides Expires:

   The presence of an Expires header field with a date value of some
   time in the future on a response that otherwise would by default be
   non-cacheable indicates that the response is cacheable, unless
   indicated otherwise by a Cache-Control header field (section 14.9).

Since this is not really realted to Date header changes, I will 
probably submit a separate bug report.
