I can't comment on the CSS for layer 7 routing, but we use the F5 LTM (BigIP) to do plenty of L7 manipulation via iRules.
Depending on the load on the VIP and the horsepower of the load balancer you would do well to stay out of manipulation that has to do with any body content and use the HTTP headers exclusively, like cookie values, hostnames, etc. Good luck. -wil On Mar 10, 2011, at 10:48 AM, Sam Hall wrote: > Hi Guys > > We have a couple of Cisco CSS11501's and are exploring the possibility if > they can load balance based on text found in packets i.e. "regular > expression"... > > We need to migrate individual client's traffic one by one to a new > environment, this is a TCP 443 session that has no context path and > destination IP and port needs to stay the same, so L3-L5 redirection is not > possible. > > Thought that there must be some L7 inspection that could find a key word i.e. > client name in the packet and direct that client to the new environment?
