You need to send information in the header that tells the server that this is a
POST request. I am assuming that you are using the URLConnection class. After
getting an instance of that class, call
URLConnection.setRequestProperty("CONTENT-TYPE",
"application/x-www-form-urlencoded"). The other header you might need to set is
"REQUEST_METHOD" with a value of "POST".
More information on how to do this is in example 10-4 of Java Servlet
Programming, Hunter and Crawford, O'Reilly 1998 (http://www.servlets.com)
