Hello,
Yeah, but this is not a solution.
I will have main server and few mirros.
Mirrors will be synced with main twice a day.
If request comes to mirror and there is no such file, it must me
proxied to main site. Cached request will be stored for 12 hours for
example.
After 12 hours i will have requested file in my docroot and it should
be servers bypass of mod_cache
Such config is not possible?
