5XX Error Redirect

We have added two new rules that will allow you to do some thing like this on the next release of BigIP. If you have the TrafficShield beta, you should be able to try this out.

              when HTTP_REQUEST {
                  if {[HTTP::method] == GET} {
                      set request [HTTP::request]
                  }
              }
 
              when HTTP_RESPONSE {
                  if {[info exists request] && ([HTTP::status] >= 500)}{
                      set server [LB::server addr]
                      HTTP::retry $request
                  }
              }
  
              when LB_SELECTED {
                  if {[info exits server] == 0} {
                      return
                  }
                  if {$server == [LB::server addr]} {
                      LB::reselect
                      set server ""
                  }
              }

For the current version of BigIP you will have to write a rule that looks like this.

when HTTP_RESPONSE {
   if {[HTTP::status] >= 500} {
        HTTP::redirect "www.host.com/try/again/page"
   }
}
