Hi,
Here is the request and response transaction that should
have (I think) returned a 304 Not Modified. Previous to this
request/response, I had already requested the resource and verified that it was,
in fact, in the cache on disk...

Subject: mod_cache does not return a 304 Not Modified
Hello,
I may be missing
something in my Apache configuration, or maybe this is a well-known
problem....But, I can't seem to get mod_cache (with mod_proxy and
mod_disk_cache) to return a 304 Not Modified response even when all of the
headers of the in the HTTP request should produce a 304 response. (of
course, I can get a 304 Not Modified response IF I include a "Cache-Control:
max-age=0" header, but the 304 response in that case is actually from the origin
server, not from Apache).
I've looked at the
code a little bit (Apache 2.0.50), and at first glance, it seems as though
proper 304 response handling might not actually be fully implemented yet.
Is that actually the case, or am I just missing something.
Thanks,
Mike.
