Refreshing modified content

[Paulo Paracatu]

If I understood it, the purging method isn't automatic, right? I'd need to
purge the content everytime it is modified.
This is kinda stupid... I host more than 10k sites, modifying files
everytime. If I set a high TTL, the backend will be happy and the webmaster
will be angry. If I set a low TTL, the webmaster will be happy, but the
backend will die. Plus, there is no point using a cache if the TTL is low.
