If it's true, then it becomes interesting to ask about the initial
congestion window used by IIS. For example, if you send a TCP segment
advertising a 60K window and containing an HTTP request for a large
HTTP document, will IIS blast 40 packets at a victim forged as the IP
source address? Or will it send only 2 or 4 segments?
It sounds easy to test, and so wrong-headed that it must all be false.
Even the embrace and extenders in Redmond are that foolish...well,
not always. Some of their PPP "enhancements" weren't far off.
