Hi,
I submitted a simple patch that fixes the above mentioned
PR, and then some.
1. All of the Cache-Control request directives are ignored.
As a consequence, end-to-end reload is for example not
possible. Originally ap_cache_check_freshness() read the
Cache-Control header from ((cache_handle_t) h)->req_hdrs.
Turns out this never contains the Cache-Control header. The
patch changes this so it is read from the request record
instead ((request_rec)r->headers_in. This is also what is
done in Apache 2.2.4 which does not exhibit this problem.
2. Responses to requests containing Cache-Control: no-cache
are not cached. The way I understand RFC2616, the no-cache
request directive should prevent a cache from serving a
cached response to such a request, but not from saving it in
cache. Apache 2.2.4 behaves as I would expect it to, i.e.
saves the response (provided it is cacheable).
I would love to move to 2.2.4, but I am prevented to do so
for the next 12 months by dependencies to third-party
modules.
