iRule for LTM to send HTTP Error code

Use the HTTP_RESPONSE event to capture the errors you care about - from the docs (http://devcentral.f5.com/wiki/default.aspx/iRules/HTTP_RESPONSE.html) they have an example and links to tons of others:

 

 
 when HTTP_RESPONSE { 
   if { [HTTP::status] contains "404"} { 
     HTTP::redirect "http://www.siterequest.com/" 
   } 
 } 
 

 

 

You could easily capture that error code and HTTP::retry against it, redirect it, serve back your own page, etc. - the sky is the limit!
