I got the answer: Quote:Hi there and thank you very much for the positive feedback!
Although Cassini itself does not limit inbound connections number, Windows does. Windows XP Pro allows 10 inbound connections. This means that given 1000 connections per minute, or 17 per second, each request would have to be handled in less than half a second in order to support this scale. This would be risky. Windows 2003 Server Web Edition would probably be a better choice and is not terribly expensive.
But since current version of UltiDev Cassini does not support "keep-alive", the effect of limited number of inbound connections is mitigated because connections from one client are released and can be reused by another as soon as the response is served, so if applications themselves perform well, even on Pro and Home versions of Windows your application will be able to serve more quasi-parallel user sessions than the limit of inbound connections. As the number of concurrent users grows, the app will feel less responsive, but it will take quite a few users to start getting connection timeouts even on Windows Home and Pro.
Best regards,

Yes, that's the one. Windows limits inbound TCP connections for all listeners, but current version of UltiDev Cassini always closes connections regardless of keep-alive headers, so in effect it can support more concurrent users than IIS in its default configuration - at the expense of slightly slower performance. Upcoming UltiDev Cassini releases are likely to add support of keep-alive.
Best regards,
