cache returned header in 304

[Benoit DOLEZ <bd...@exosec.fr>]

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.

Benoit
