2. Not entirely sure here. Reading the HTTP/1.1 http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.3.5
It states:
"If a cache uses a received 304 response to update a cache entry, the cache MUST update the entry to reflect any new field values given in the response."
I suspect that is what we're seeing in mod_proxy. But I just realised that I have some reading to do, the stuff about weak and strong validator didn't make much sense to me...

E.g. first request comes into mod_proxy and it can't find the requested resource in its cache. It forwards on to my tomcat who responds with something like: HTTP/1.1 200 Content-Type: image/gif Content-Length: 12345 Second call comes into mod_proxy this time with an "If-Modified-Since" for the same resource. mod_proxy needs to revalidate its cached entry against tomcat and does an "If-Modifed-Since" against tomcat and tomcat answers: HTTP/1.1 304 Content-Type: text/html Content-Length: 0 At this point mod_proxy updates it's cached entry and ends up with a gif that has got a Content-Type set to text/html. Further requests to mod_proxy without "If-Modified-Since" results in GIFs with strange content types. Thank god for IE not trusting the content type :)
Nope, that's not it, but it's a good catch. We don't keep proxied content
cached... Thanks a lot for the clarification...
If I got it right there are 2 errors:
1 - Tomcat should not send a Content-Type nor Content-Length.
2 - mod_proxy should complain because we are sending "garbages" or ignore the "invalid" headers.
