Clear apache server memory cache

I'm using mod_mem_cache in my apache web server to cache static co开发者_如何转开发ntent, but I need to know how to clear the cache. For disk cache I guess you can just erase the directory or use htcacheclean? But I'm not sure what to do for memory cache (without restarting)

I would consider using an external cache server (like Memcached) with Apache's mod_memcache_cache. Guide here.

You have very easy access to it from anywhere and it makes dumping the contents into the Gulf when you don't want them anymore very simple.
