[SOLVED] Has anyone gotten mod_mem_cache to work on Apache?

I'm trying to play with Apache's new caching stuff (using 2.2.10), but the mem_cache part of it doesn't seem to work. I'm using Apache as a reverse proxy, and I want it to cache the responses from the backend server. If I use 'CacheEnable disk /', it works (apache doesn't continue to make requests against backend). If I use 'CacheEnable mem /', it doesn't appear to do anything. Here's an example of some of the directives I'm trying:

# For mem_cache (Doesn't work?)
CacheEnable mem /
#MCacheSize 131072
#MCacheMaxObjectCount 1000
#MCacheMinObjectSize 1
#MCacheMaxObjectSize 2048

# For disk_cache (Works fine?)
CacheEnable disk /
CacheRoot /dev/shm
#CacheDefaultExpire 86400
#CacheIgnoreCacheControl On
#CacheIgnoreNoLastMod On
#CacheMaxExpire 604800
#CacheStoreNoStore On

Has anyone tried using mem_cache successfully?

Thanks!

Just in case anyone is curious, all of the information I could find points to mod_mem_cache being broken on 2.2.x. I'm using mod_disk_cache to tmpfs as a workaround.
