Reverse Proxy - Issue in 0.8.36/.37

[Kevin]

Realized I couldn't edit my post. 

No issues are seen with reverse proxies (that we can tell) when using standard ports. It appears to be only on non-standard ports. Firewall had been disabled for testing as well.

tcpdump shows the connections going out and a response coming back but it immediately drops to a 'Bad Gateway'. Downgraded to 0.7.xx (newest) and the issue was immediately resolved. (Exact same config file, simply a restart of the service and it started working again with 0.7) 

This issue occurred on two different systems, two different datacenters.

FreeBSD 8.0 x64 / with kqueue
