I know you're asking a programming question, but you could avoid the whole thing by abandoning the effort to write an ISAPI filter, and instead use an off-the-shelf general purpose rewriter, like IIRF .
If you really want to write and maintain a custom ISAPI Filter, I highly recommend two things.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
