Description

We should leverage browser caching and a reverse proxy to make GitBlit responsive. It currently marks all responses as no-cache, which is too aggressive.

We are currently running it behind Apache as a reverse proxy. I'm fine with trying to improve caching here. If swapping Apache for $somethingElse is necessary, I'm fine with that too.

This is now deployed with a default expiry of 5 minutes. Look good to you Ori?

5 minutes seems too short -- it should be a week or more for some static assets -- and I don't think "Cache-Control: private, must-revalidate" is appropriate for an unauthenticated, read-only view of Git data.

5 minutes was mostly for testing. That being said, I think this setting affects too many things and not just resources. Maybe we need to hack it a bit.
