Doru, I meant: look at ZnServer and friends for inspiration, not to solve the problem of how to write a simple TCP server.
If you do just: ZnServer startDefaultOn: 1701 and then talk HTTP over telnet, it will work as expected: $ telnet 127.0.0.1 1701 Trying 127.0.0.1... Connected to localhost. Escape character is '^]'. GET / HTTP/1.1 HTTP/1.1 200 OK Content-Type: text/html;charset=utf-8 Content-Length: 1195 Date: Fri, 24 Feb 2012 12:51:03 GMT Server: Zinc HTTP Components 1.0 <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd";> <html> <head> <title>Zinc HTTP Components</title> <style type="text/css"> body { color: black; …. Writing your own delegate means handling HTTP requests and answering with HTTP responses. (Zn contains a lot of these). But I am not sure that you should do that for your problem, on one hand it might be overkill, on the other hand, HTTP _is_ one of the easiest protocols, not need to invent something new. If you use HTTP, you get all you need with Zn. The question is: what is on the other side ? what is the client ?
