Our current Apache installations are running Apache 2.0. Now we'd like to add some Rails applications and plan to run them on Apache with Phusion Passenger. I've gotten conflicting reports about whether we need to upgrade Apache to 2.2 in order to use Passenger (a consultant I highly respect recommended that; someone from Phusion says 2.0 should be fine.
Anybody running Passenger with Apache 2.0 in production?
