[users@httpd] Problem with HEAD requests via mod_cache and mod_proxy

[Sridhar Basam <ba...@stream.aol.net>]

Hey,
       I am using apache 2.2.3 with mod_proxy and mod_cache in reverse 
proxy mode. I am seeing a problem with the response to HEAD requests in 
this setup.

If you send a HEAD request for content that is cached but expired, 
mod_cache correctly sends a conditional request to the origin but that 
"304 Not Modified" response from the internal server isn't being 
translated to a 200 response before passing it to the user. The response 
to the end user is a 304 and the previously cached file on disk is 
purged from the cache.

Can someone else using mod_proxy and mod_cache verify this is the case. 
I am running a stock apache version on RedHat AS4.

thanks,
    Sridhar
