title: Calling servlets from client side
body: <p>I had been reading on servlets and all books deal with invoking a servlet by means of a form (POST requests).
  I was wondering if there are other means to invoke a servlet by a client.</p>
  
  <p>Here is my understanding: For POST requests to a servlet, we use a link thus making a GET request on that servlet and in the servlet we need to call doPost() from doGet().</p>
