If this would be a param for proxy_cache_path we could build a distributed cache cluster by simply copying cache files to other nodes. Making this a param would not hut performance if you don't want this behavior. The functionality is already there, because nginx loads metadata from files on startup. Is this a valid feature request or does no one care aboout clustering nginx caches? -- Thomas Posted at Nginx Forum: http://forum.nginx.org/read.php?2,252275,255788#msg-255788 _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
