Please tell me more about the web application. Tell me howmany users it should handle and what it should do exactly. Tell me why you are considering to use Micro'Junk'? Tell me what computer you are running (processor?, Ram?) Tell me how much time you have left.
And finally: are you sure you know what your talking about? ASP runs on IIS so you may be bound to use it or you can make a C++ component interfacing with ASP. But that all depends on what the application should do.
Oh and why did you come to this forum!! It's all about JAVA you know! :) It's pretty much M$ solutions against SUN's solutions and you are suggesting M$ on a SUN forum. (weird)
