No. It simply tells Squid that this peer is a web server and expects requests to be sent in web server format and not proxy format. Note: many web servers accepts both formats (actually required by HTTP/1.1). As Amos already mentioned there is some additional minor twists as originserver also tells Squid that the peer is NOT an HTTP proxy, so it can't sent proxy type requests to it. All in all, originserver flag basically only makes sense in reverse proxy modes, and then only when forwarding requests to acutal web servers as peers. Normally those are parent peers to the reverse proxy. Regards Henrik
