Please document git-http-backend/Apache timeout interactions

Hi,

I am running git-http-backend behind Apache as suggested in git-http-backend(1). However, what it fails to mention is that git-fetch-pack seemingly can be very slow in sending its request. Consequently, mod_reqtimeout (on by default, as I understand it) kicks in as an anti-DoS measure, and the user sees a 408 (timeout) error.

Seemingly the simplest fix is to turn off mod_reqtimeout in the vhost serving git (potentially with some <IfModule> around it):

   RequestReadTimeout header=0 body=0

Would you consider adding this to the documentation?

Thanks!
