I've got an update from ASL.

ASL T-WAF runs an optimised version of Apache with Mod Security and Mod_proxy in front of litespeed. (note : this hardly adds any latency on our server, we get 15ms responses even with mod_security in T-WAF proxy).

This is what is happening :

I'm getting the following error from mod_proxy : "proxy: error reading status line from remote server"

"proxy: error reading status line from remote server" error message caused by the race condition that the backend server closed the pooled connection after the connection check by the proxy and before data sent by the proxy reached the backend

1) Client connects to the T-WAF (local reverse proxy)
2) T-WAF checks connection is live
3) Litespeed goes away
4) T-WAF proxy doesn't get the data from litespeed

Do you have any suggestions about how I could get litespeed to play well running behind a reverse proxy ?

Thanks
