Marc, I know you have answered this before, but I just wanted to know, where is the web application file or files on Gambit Scheme?

I posted the following message to comp.lang.scheme not too long ago with the code for a barebones HTTP server.

Here's a barebones HTTP server for Gambit. It should be fairly obvious how to extend this to your specific requirements, such as handling forms. If you need something more general check out the examples/web-server directory in the Gambit source code distribution.
