Subject: RE: [users@httpd] Clearing cache selectively on Apache + mod_cache

That sounds like a possible way to go. However, this spills into another qu=
estion. I have the CacheIgnoreCacheControl directive set to "On" for mod_ca=
che. I know that this means "no-cache" is ignored in the request. Does it a=
lso ignore "max-age", or can I force the cache to clear by using "max-age" =
even if CacheIgnoreCacheControl is on?

Thanks,

Try these combinations of headers, comment from cache_util.c:

    /*

     * on a few things, in this order:
