But is the last bit really > nessesary for a resource that is only available in one format? There's no "accept-type". I suggest you read the RFC rather than make wild guesses. But anyway, when URL /foo is resolved to file $path/foo.html.nb , mod_negotiation assumes there could be other negotiated options for either or both of .html and .nb, and uses Vary to tell the client. It may not always be necessary, but it's safe. Even if there's nothing there now, the fact you're using content negotiation suggests there might be at other times. -- Nick Kew Application Development with Apache - the Apache Modules Book http://www.apachetutor.org/ --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
