Hello, I am trying to implement a complete web application from the ground up, with the objective to convince myself and others that 1) it is possible, 2) it is powerful and 3) it is more expressive to do such a thing in Haskell. I managed to get to the point where I can handle users lifecycle with DB handling, and I have a CLI application. I have a World that stores Session objects, containing a "continuation" of possible functions to call. The problem I am facing now is how to handle (Fast)CGI requests, given that each request seems to be served by a dinstinct invocation of a function, and share the World between all connections. I have a vague idea that this could be handled by creating some CGIT transformed monad operating on a TVar World (that's what is hinted at on haskell wiki), but I am not sure how to tackle this. I asked this question on #haskell but had to leave too quickly. Some people there seems to think this is something very common that has been resolved over a hundred times. Once would be enough for me, and I would be very happy if someone could point me to the right direction or provide some sample code for this.
