Hiding reals servers IP address in http response

A while back, Deb posted a nice method for removing all instances of a header (it will remove multiple instances of the same header):

when HTTP_RESPONSE {
    strip all instances of the existing headers
   foreach header {X-Cache Via} {
      while { [HTTP::header exists $header] } {
         HTTP::header remove $header
      }
   }
}

You could also remove the Date, Server and X-Powered-By headers to reduce the amount of superfluous info about the web application given back to the client.
