But, if you would like to have more traditional URLs in addition to the
continuation/cryptic ones, you can use the web-server/dispatch library:


It starts with a bit of guide to orient you before the reference manual.

It allows you to create URLs like


and if during the generation of that page you hit a continuation operation,
the URL will be something like


where the last "clean" URL is inside of the current "ugly" URL.

I find that most people want to mostly use web-server/dispatch but
occasionally use continuations for the sequential computations in their Web
