Well, you need it for Comet (unless you use the APR Connector which has similar functionality). I have a project that hasn't moved to Comet yet, but probably will do sometime this year, since the prototypes show a lot of promise. With Comet, you are basically setting up long-lived connections with the option of server-push (so you have some protocol wrapped in HTTP, e.g. SOAP), that needs to run for a long time before producing results.
You also get 'sendfile' support, so if your site sends a lot of very large static files, you can win this way (mostly the reason to use it on Windows). Even with conventional Servlets, you can get a benifit for high-volume sites. But this depends on your OS, how much hardware you want to give it, and your Java vendor. Using the NIO Connector means that threads aren't tied up waiting on HTTP Keep-Alives, so if the cost of having 5000 threads blocking on input is high for you (e.g. true for Linux systems with older kernals), then the NIO Connector can lower your cost. For Solaris with Sun's JVM, Sun has implemented NIO better than APR has, so it should be a no-brainer. Like with most things, profile it against the app that you are actually using. That is the only way to know for sure if it is right for you ;). "Johnny Kewl" <[EMAIL PROTECTED]> wrote in message news:[EMAIL PROTECTED] Cant contain my curiousity anymore? What practical applications is this been used for? I see theres a lot of control over the socket etc... but what are you guys actually doing with it?
