Hello,
My configuration is :
- web server with Apache 1.3.33 (WEB)
- reverse-proxy with Apache 1.3.33 (tested with ProxyPass[Reverse] and
RewriteRule) (PROXY) (no DefaultType configured)
- reverse-cache-proxy with Apache 1.3.33 (CACHE)
When I do a request on a picture that return 304 (not modified) on WEB, it
returns
------------------------------------------------
HTTP/1.0 304 Not Modified
Date: Tue, 24 May 2005 17:23:36 GMT
Server: Apache
ETag: "7af-33-4194f50a"
------------------------------------------------
When I do the same request on PROXY, it returns
------------------------------------------------
HTTP/1.0 304 Not Modified
Date: Tue, 24 May 2005 17:23:30 GMT
Server: Apache
ETag: "7af-33-4194f50a"
X-Cache: MISS from WEB
Connection: close
Content-Type: text/plain
------------------------------------------------
And then the cache (CACHE) stores 'test/plain' as Content-Type, and remove the
good 'image/png' one.
There was an error like this with 'Content-Length': no content are returned
but "false/default" headers are store in the cache.
The patch, I send, remove all critical Content-... headers.
