Problem Statement

The browser is the new GUI !

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.

Let's start with the solution:

MODULE access;

FROM  InOut   IMPORT  WriteString, WriteLn;

BEGIN
   WriteString ("Content-Type : text/plain");
   WriteLn;
   WriteLn;
   WriteString ("Hello web wide world.");
   WriteLn
END access.
