The browser is the new GUI !



Task

Serve our standard text   Goodbye, World!   to   http://localhost:8080/   so that it can be viewed with a web browser.

The provided solution must start or implement a server that accepts multiple client connections and serves text as requested.

Note that starting a web browser or opening a new window with this URL
is not part of the task.

Additionally, it is permissible to serve the provided page as a plain text file (there is no requirement to serve properly formatted HTML here).

The browser will generally do the right thing with simple text like this.




var port = 8080;
var protocol = Socket.getprotobyname("tcp");
 
var sock = (Socket.open(Socket.PF_INET, Socket.SOCK_STREAM, protocol) || die "couldn't open a socket: #{$!}");
  # PF_INET to indicate that this socket will connect to the internet domain
  # SOCK_STREAM indicates a TCP stream, SOCK_DGRAM would indicate UDP communication
 
sock.setsockopt(Socket.SOL_SOCKET, Socket.SO_REUSEADDR, 1) || die "couldn't set socket options: #{$!}";
  # SOL_SOCKET to indicate that we are setting an option on the socket instead of the protocol
  # mark the socket reusable
 
sock.bind(Socket.sockaddr_in(port, Socket.INADDR_ANY)) || die "couldn't bind socket to port #{port}: #{$!}";
  # bind our socket to $port, allowing any IP to connect
 
sock.listen(Socket.SOMAXCONN) || die "couldn't listen to port #{port}: #{$!}";
  # start listening for incoming connections
 
while (var client = sock.accept) {
  client.print ("HTTP/1.1 200 OK\r\n" +
               "Content-Type: text/html; charset=UTF-8\r\n\r\n" +
               "<html><head><title>Goodbye, world!</title></head>" +
               "<body>Goodbye, world!</body></html>\r\n");
  client.close;
