CirrostratusThe overhead for parsing the HTTP headers and checking the URI is very minimal. However, if you have the ability to handle the redirect at the web server, it would be more efficient from the LTM perspective.
You could do some sample load testing with and without the rule to get an idea of the latency added. You could also compare the TMM CPU usage with and without the rule. I would guess the differences would be low enough that it would be difficult to measure.
