404 question

I am trying to send a redirect to a 404 page but also return a 404 status code to the web browser. How is this accomplished? I have the following iRule, but it only returns a blank page:

 

 

 
 when HTTP_REQUEST {   
   if { [HTTP::uri] contains "notfound.jsp" } { 
   event disable all 
   }   
 } 
  
 when HTTP_RESPONSE { 
   if { [HTTP::status] == "404" or [HTTP::status] == "500"}{ 
   log local0. "A 404 was hit" 
   HTTP::respond 404 Location "http://www.validdomainhere.com/error/notfound.jsp" 
   } 
 }

 

 

I would rather not host the content on the BigIP, so I'm hoping to redirect to a valid page but keep the 404 error code.

 

 

Thanks!

    If you send a 404, the client won't use the Location header for anything. If you want LTM to send a 404 with content, you'd have to send the content from the iRule. I suppose you could use HTTP::retry to do something fancy like get the response content from another host and send that back to the client, but it would probably add a significant amount of complexity to your configuration and latency to the response time.
