Subject [users@httpd] apache-2.0.42 mod_cache fails to observe "no-cache" header
Date Wed, 11 Dec 2002 19:44:47 GMT
Dear Apache users,

Platform: Linux Red Hat 7.2, apache 2.0.42 with mod_proxy and mod_cache.

Apache server is acting as a reverse proxy using ProxyPass and
Caching is also active using mod_cache.

I have a situation where apache caches a document that has "Pragma:
I have read the rfc2616 and 2109 and looks like word "SHOULD" is used
instead of MUST for this particular directive.
It is not clear under what circumstances mod_cache will store a document in
local cache and when it wouldn't?!
Looks to me like some documents with "Pragma: no-cache" are not cached, but
some others are?!
Does this depend on the doc type or some other headers? I have noticed that
my offending document was a "301" redirection.

Here is the doc header as it was stored in apache cache:

Server: Netscape-Enterprise/3.5.1^M
Date: Wed, 11 Dec 2002 18:59:39 GMT^M
Pragma: No-cache^M
Location: /myhome^M
Via: 1.1^M
301 Unknown reason
