Hi all- Using Apache 2.2.0- I've read some other threads in the archives reporting weirdness with this- I am trying to set up a reverse proxy/cache, and have concluded that it simply does not work. The proxy portion works just fine, and the cache portion works just fine for local files, but mod_cache does not serve-from-cache any proxied content- I have tried with various proxied content, and regardless of it's reported cache-ability I have set the proper mod_cache options to ignore any expires headers etc, and always cache: (behavior is broken with both mem_cache and disk_cache) This is what all the requests looks like, proxying a request for Opera's logo: (the first "fail to connect" is because of ipv6 support- ignore it) Mod_cache sees the request: [Thu Mar 30 21:36:37 2006] [debug] mod_cache.c(129): Adding CACHE_SAVE filter for /img/operalogo.gif [Thu Mar 30 21:36:37 2006] [debug] mod_cache.c(136): Adding CACHE_REMOVE_URL filter for /img/operalogo.gif Proxy portion, works just fine: [Thu Mar 30 21:36:37 2006] [debug] mod_proxy_http.c(54): proxy: HTTP: canonicalising URL //www.opera.com/img/operalogo.gif [Thu Mar 30 21:36:37 2006] [debug] proxy_util.c(1373): [client 192.168.1.101] proxy: http: found worker http://www.opera.com/ for http://www.opera.com/img/operalogo.gif [Thu Mar 30 21:36:37 2006] [debug] mod_proxy.c(736): Running scheme http handler (attempt 0) [Thu Mar 30 21:36:37 2006] [debug] mod_proxy_http.c(1661): proxy: HTTP: serving URL http://www.opera.com/img/operalogo.gif [Thu Mar 30 21:36:37 2006] [debug] proxy_util.c(1754): proxy: HTTP: has acquired connection for (www.opera.com) [Thu Mar 30 21:36:37 2006] [debug] proxy_util.c(1811): proxy: connecting http://www.opera.com/img/operalogo.gif to www.opera.com:80 [Thu Mar 30 21:36:37 2006] [debug] proxy_util.c(1911): proxy: connected /img/operalogo.gif to www.opera.com:80 [Thu Mar 30 21:36:37 2006] [debug] proxy_util.c(2005): proxy: HTTP: fam 28 socket created to connect to www.opera.com [Thu Mar 30 21:36:37 2006] [debug] proxy_util.c(2016): (65)No route to host: proxy: HTTP: attempt to connect to [2002:42eb:b46b::2]:80 (www.opera.com) failed [Thu Mar 30 21:36:37 2006] [debug] proxy_util.c(2005): proxy: HTTP: fam 2 socket created to connect to www.opera.com [Thu Mar 30 21:36:37 2006] [debug] proxy_util.c(2101): proxy: HTTP: connection complete to [2002:42eb:b46b::2]:80 (www.opera.com) [Thu Mar 30 21:36:38 2006] [debug] mod_proxy_http.c(1443): proxy: start body send Mod_cache apparently deciding it's cacheable: [Thu Mar 30 21:36:38 2006] [debug] mod_cache.c(602): cache: Caching url: /img/operalogo.gif [Thu Mar 30 21:36:38 2006] [debug] mod_cache.c(608): cache: Removing CACHE_REMOVE_URL filter.

(I have confirmed that the disk cache is caching as well- I can see the actual objects on disk) In contrast, this is what it should look like (serving a cached local file): First request: [Fri Mar 31 12:12:42 2006] [debug] mod_cache.c(129): Adding CACHE_SAVE filter for /index.html [Fri Mar 31 12:12:42 2006] [debug] mod_cache.c(136): Adding CACHE_REMOVE_URL filter for /index.html [Fri Mar 31 12:12:42 2006] [debug] mod_cache.c(602): cache: Caching url: /index.html [Fri Mar 31 12:12:42 2006] [debug] mod_cache.c(608): cache: Removing CACHE_REMOVE_URL filter.

Reload of page: [Fri Mar 31 12:12:59 2006] [info] Incoming request is asking for a uncached version of /index.html, but we know better and are ignoring it [Fri Mar 31 12:12:59 2006] [debug] mod_cache.c(261): cache: running CACHE_OUT filter [Fri Mar 31 12:12:59 2006] [debug] mod_cache.c(275): cache: serving /index.html So- it appears to me that the CACHE_OUT filter is never being run for some reason when the proxy is in place- Has this *ever* worked? I would be happy to drop back to a working version at this point, but nowhere on the great interweb can I actually find a report of this working as it is supposed to. -SS --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
