http content rewrite

Hi,     I'm looking for some help writing my first iRule.     We are quering a remote domain for an xml feed, but often the returned content begins with garbage - please see example below:...
application delivery
dev
devops
irules

I would set replace to 0 as a default in the HTTP_REQUEST event or you will get a undefined variable error when trying to access it in the other events.

when HTTP_REQUEST {
  set replace 0
  if { [matchclass [HTTP::host] equals $::BadServers] }{
    set replace 1
  }
}

Otherwise, it looks good to me...
