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:<div><br></div><div><a href="http://docs.racket-lang.org/web-server/dispatch.html">http://docs.racket-lang.org/web-server/dispatch.html</a></div> <div><br></div><div>It starts with a bit of guide to orient you before the reference manual.</div><div><br></div><div>It allows you to create URLs like</div><div><br></div><div>/posts/456</div><div><br></div><div>and if during the generation of that page you hit a continuation operation, the URL will be something like</div> <div><br></div><div><div>/posts/456;gobbledygook</div><div><br></div><div>where the last "clean" URL is inside of the current "ugly" URL.</div><div><br></div><div>I find that most people want to mostly use web-server/dispatch but occasionally use continuations for the sequential computations in their Web app.</div> <div><br></div><div>Jay</div><div><br></div><div class="gmail_quote">On Sat, Dec 17, 2011 at 11:39 AM, Shriram Krishnamurthi <span dir="ltr"><<a href="mailto:sk@cs.brown.edu">sk@cs.brown.edu</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"> Hi R.
