how to know what cache file for what page ?
At the moment when you create a cash file with hash name - can you write this filename to an additional MySQL fiield of speedcache_urls table ?
This case an advanced admin will find that record if necessary.
But still the mess - thousands of cache files under /speedcache/ folder and admin has no a chance to know which file for what page.
Something similar was discussed about a year ago - are there any changes ?
I still do not see such a necessary "control enhancement" in changelog of your script.
