Class FlatFileServlet

java.lang.Object
  javax.servlet.GenericServlet
      javax.servlet.http.HttpServlet
          examples.flatfile.FlatFileServlet

All Implemented Interfaces:

Serializable, javax.servlet.Servlet, javax.servlet.ServletConfig

public class FlatFileServlet
extends javax.servlet.http.HttpServlet

This is a simple example of a HTTPS servlet that uses KeyMaster. The idea is that it is only accessible via Secure Sockets Layer (SSL) and uses a ASCII file to authenticate the user instead of checking the private key files. The file has a number of users and each user has a token which will be returned as a response. The response is formatter using StreamLinkFormatter only. This can easily be extended though.
The servlet checks the URL that requested it to make sure that the URL used HTTPS and not HTTP.
