Hi Adrian,

 

 

I did some basic testing of a basic (limited HTTP only) web proxy iRule. I wouldn't consider it fully functional, but you could use it as a start. It would probably be better to implement a true web proxy and have LTM load balance or route to that though.

 

 

LTM like Web Proxy (Squid)
