To issue a redirect when the pool is down, specify a Fallback Host in the HTTP profile.

 

 

I have just uploaded an iRule that improves on this behavior, because the Fallback Host behavior is not ideal. See http://devcentral.f5.com/wiki/default.aspx/iRules/Webserver_Down_Message.html

 

 

As I point out on that page, though, 503 is the magic status code that makes the code fail. Can anyone shed some light on this bug?
