mod_mem_cache was removed in Apache 2.4 so all the bits of configuration gated by the IfModule are currently irrelevant. The replacement is socache, the in-memory version is "shmcb" (can also hook up to memcache, etc.). Enable the socache module, and switch the cache matching parts to use socache and then fall-back to disk cache (this is what it says this will do in the manual [1]) The other part of this is to turn the CacheQuickHandler off. The manual says about this [2] In the default enabled configuration, the cache operates within the quick handler phase. This phase short circuits the majority of server processing, and represents the most performant mode of operation for a typical server. The cache bolts onto the front of the server, and the majority of server processing is avoided. I won't claim to fully understand how our mod_rewrite rules and mod_proxy all hang together with phases and what-not. But emperically with this turned on (default) we do not seem to get any caching on the tenant status pages, and with it turned off we do. I've deliberately removed IfModule gating as well. This actually hid the problem and made it much more difficult to diagnose; it is much better if these directives just fail to start Apache if we do not have the modules we expect to have.
