title: When to use doGet, doPost and service
body: <p>I was wondering about these servlet methods. i know something about these methods like</p>
  
  <ul>
  <li><code>doPost</code> has no limitations on paramater numbers while <code>doGet</code> has.</li>
  <li><code>doGet</code> is faster than <code>doPost</code>.</li>
  <li><code>doPost</code> is secured than <code>doGet</code>.</li>
  </ul>
  
  <p>And my question is, as these methods takes same parameters and does the process which we implement. then what is the <code>major difference</code> between these methods and <code>At which specific situation each of this method is used to process</code>.</p>
