Adding a uri if one doesn't exist

Does this work:

when HTTP_REQUEST {
  if {[string equal [HTTP::uri] {/}] } {
    HTTP::uri {/ghi/}
  }
}

If it doesn't, change the "Type" configured for the virtual server to "Standard" and retry.

Also, was it clear to you that this causes BIG-IP to modify the HTTP request passing from the user to the server? Therefore, even though the content is coming from http://www.example.com/ghi/, the user's web browser will still show http://www.example.com/ in the address field.
