public class S10_HTTP_Access
extends javax.servlet.http.HttpServlet

This class is used to treat http user requests. It is a servlet which is connected to eMATgine server throught a socket. This socket connection is secured or not thanks to ElGamal cryptix encoding. This servlet is called by the user entering in its Web browser the following address: http://host/servlet/org.ematgine.threads.admin.S10_HTTP_Access if myservlet.class located in /install_doc_base_dir/servlets/org/ematgine/threads/admin
