Package: apache2-mpm-event Version: 2.2.14-2 Severity: normal
CacheIgnoreURLSessionIdentifiers fails to work properly, when two session identifiers are used. Background: I'd like to use apache mod_mem_cache to accelerate a facebook app. I'd like to strip the fb_sig_time and fb_sig request parameters, so request from the same user, for the same pages would have a chance to hit the cache. The application servers is using SCGI, I check from the SCGI servers log, if the request was served from the apache cache, or by the application server.
