What you describe migth be actually a DNS related problem. If dilbert.com doesn't resolve well using your current NS/resolver library combination, some applications might wait to receive an answer or a time out for the previous queried addresses before processing the next request(s). This behaviour can be avoided using a asynchronous resolver implementation - in this case the application wouldn't wait for a reply before performing the next queries. AFAIK the OpenBSD resolver library is not asynchronous, someone please correct me if I'm wrong here. However, if you can reproduce the behaviour using another browser, Opera comes to mind, then you can exclude Firefox from your list of suspects and the next step would be changing the NS you are using at this moment. -- Digitally yours, Florin Iamandi (Slippery) Reason is the first victim of emotion. -- Scytale, Dune Messiah [demime 1.01d removed an attachment of type application/pgp-signature]
