Hi Adrian,

 

 

I think it would be a very bad idea to use that rule in a production environment. The iRule doesn't even start to implement all of the requirements from the HTTP 1.1 or 1.0 RFCs. It would be much more reliable and efficient to use a true web proxy or collection of proxies which LTM load balances compared with this rule.
