Running into a problem

Write a simple iRule to redirect to error page when the BigIp see a 404.But when I add the rule to a VIP the server will not even display a page. Took a trace of the traffic and the client makes the connection request a valid page but never get a responce back from the web server. Below is the rule, I have a default pool to catch traffic the rule does not. Thanks

 

 

 

when HTTP_REQUEST {

 

if { [HTTP::status] eq "404" } {

 

redirect to "http://10.10.10.1/en_US/error.html" }

 

}
