[Cuis-dev] updating WebServer code - begging for help

[Mariano Montone]

Hi Mark,

don't put the code that does the response inside a block. Once you pass 
that block you cannot access it and change it anymore.

Instead, dispatch to a method, and modify that method.

initialize

    WebServer new

     listenOn: 3000;                

       addService: '/hello' action: (MessageSend receiver: self selector: #helloWorld:)

Then implement the #helloWorld: method and change a piacere.

Also, I would not start the service when you create it. I would start 
and stop it manually so you have control.

I attach an example. Look at the class comment.

Cheers,

     Mariano
