Re: triggering servlet on GET parameters

Thank you Jay, Matthew, Jesse & David,

I'm still looking at the resources your referred me to - they are much
appreciated.

On the bright side I have the basic thing working:
https://github.com/spdegabrielle/clash/blob/master/main.rkt

I'm trying to build a very basic wiki using scribble as the wiki text!
(to replace https://github.com/racket/racket/wiki)

If you have time or are interested I'd appreciate feedback on my code.

Kind regards,
Stephen
