In your message of Mon, 11 Sep 1995 20:24:45 -0700, you mentioned a problem with cancels in an interleaved setting, such as your SCP: ``This can work, and is the strategy used in HTTP-NG for cancels and suspends; however there are a few problems. The main problem is that due to the ordered delivery of TCP Messages, any outstanding requests must be parsed before you get to the cancel/suspend. A side problem is that any data that has been placed in the send buffer by the server still gets written, even if the data has been delivered.'' Presumably this could be handled by complexifying SCP to have a way for a client to get to TCP Urgent Data, sending along at the SCP layer enough additional state for the receiver to detect what's been skipped.
