Got it. Well, while I can't see why you'd want C++ of all languages for this (Haskell seems like what you are really looking for), apache might actually be your friend here. At an old $WORK we had a number of web applications written in C++ and C (yup!), as apache modules. This way apache does most of the boring stuff such as header parsing, routing requests, config files, etc. and you do just the functional parts of your site/app. Then again, this was one of the slowest and most error-prone ways to code this up, and the guys working on this were full time C/C++ devs.
