You would have to retry a connection with a new source port. How do you handle cases where the application explicitly bound the socket to a specific source port / source IP ? Caching whether the site is able to speak ECN or not is also suboptimal if the local site is opening lots of outgoing connections, like a proxy server. (Of course, memory has gotten cheap) _And_ it is solving the problem on the wrong end. Sincerely, Lars Marowsky-Brée -- Perfection is our goal, excellence will be tolerated. -- J.
