Subject RE: [users@httpd] Reverse proxy and cache
Date Thu, 16 Feb 2006 12:10:36 GMT
All I see here is a document actually being saved to cache. It does not show the cache modules
declining the request because the document is not in cache. I can therefore only assume that
the document was NOT in cache when the request was issued.

There are request headers that will prevent a document from being served from cache, but the
debug log should show why mod_cache does not serve it from cache. Could you submit the debug
log covering 2 subsequent GET operations on the same GDF/JPG ?
