After gaining some basic understanding of web applications, I wanted to develop one in Racket. So I went to the tutorial "Continue: Web Applications in Racket <http://docs.racket-lang.org/continue/index.html>". When I reached "6 Advanced Control Flow", I saw `send/suspend/dispatch`. I didn't know what it is, so I clicked on the link <http://docs.racket-lang.org/web-server/servlet.html#%28def._%28%28lib._web-server%2Fservlet%2Fweb..rkt%29._send%2Fsuspend%2Fdispatch%29%29>to see its documentation and saw a very complex starting sentence:
> Calls make-response with a function (often named embed/url) that, when called with a procedure from `request?` to any/c will generate a URL, that when invoked will call the function with the `request?` object and return the result to the caller of send/suspend/dispatch. I couldn't figure out the meaning of this sentence, so I went on to ` send/suspend<http://docs.racket-lang.org/web-server/servlet.html#%28def._%28%28lib._web-server%2Fservlet%2Fweb..rkt%29._send%2Fsuspend%29%29> `: > Captures the current continuation, stores it with exp as the expiration handler, and binds it to a URL. Although I knew what a continuation is, I didn't know what it is in this context. Then I gave up. I know that the web framework for Racket is very advanced. But IMHO, for the tutorial, a simpler one with some basic functionality like request handling, response sending and routing will be enough. And an advanced one would probably scare beginners like me away. Hope my experience is somewhat useful to you. Thanks, Ben
