Subject [Bug 56977] segfaults when using mod_mem_cache + mod_disk_cache on a reverse proxy with mod_proxy + mod_proxy_http

--- Comment #2 from Ruediger Pluem <> ---
Honest opinion: Don't use mod_mem_cache. It does not speed up things compared
to mod_disk_cache. mod_mem_cache's cache is not shared between different httpd
processes. So you waste more memory for getting less performance. Given that
you have enough memory in your server mod_disk_cache content is kept in the
buffer caches by the OS. If you don't use SSL stuff is send via sendfile which
moves stuff from the buffer caches to the socket directly inside the kernel. If
you are using SSL stuff will need to be MMAP which is still very fast.
