title: Difference b/w <context-param> and <init-param>
body: <p>DD elements <code>&lt;context-param&gt;</code> and <code>&lt;init-param&gt;</code> both can be retrieved by the <code>getInitParameter()</code> method, in the servlet code.</p>
  
  <p>Now the question is, how does it differentiate <code>&lt;context-param&gt;</code> and <code>&lt;init-param&gt;</code>?</p>
