POST for cache invalidating

[anakin]

Hi,
I'm new with mod_cache and would like to ask about the method of cache
being invalidated after a POST request. Does POST on /resource
invalidate the cache for /resource just like "PURGE /resource" does?
It's kind of handy feature also provided by squid and I'm wondering if
I can use it here the same way.

Thanks!

"PURGE /resource" let modcache to delete "/resource"'s local cache in disk. modcache supports "PURGE" command
"POST /resource" just let modcache pass request to mod_proxy and don't cache the response
