LB_FAILED iRule vs HTTP Fallback Host

Thanks for this note. I was using a procedure in my HTTP_REQUEST irule to redirect to an undermaint site with arguements to show the name of the site and some error text (optional to the undermaint site). However, many of these flagged problems were being skipped and the undermaint was not appearing, until I created the fallback host entry in the HTTP profile. Interesting that the path entere in the fallback host is not used in the redirect; however my internal re-direct is working now with the query fields used by my undermaint site.
