title: How to change URL of a page on button click and change the Keywords & Description of a page in asp.net?
body: <p>I have a <code>.aspx</code> page which show items hierarchically(4Levels) depending on selected category(<code>Level1</code>). I <strong>want to change the URL on button clic</strong>k of specific Hierarchy say <code>Level1</code>, <code>Level2</code>, <code>Level3</code>, <code>Level4</code> and accordingly <strong>change the Keywords &amp; Description</strong> of a page depending on <code>Clicked</code> Item of specific <code>Level</code>.</p>
  
  <p>Similar to <strong><a href="https://www.gazelle.com/sell/cell-phone" rel="nofollow">this link</a></strong></p>
  
  <p>Eg: </p>
  
  <ul>
  <li>When we click on CellPhones it shows different <code>keywords</code> &amp; <code>description</code> in meta tag</li>
  <li>When we click on CellPhones->BlackBerry-> it shows its related <code>keyword</code> &amp; <code>description</code> in meta. And most important is the <strong>URL also changes at every CLICK.</strong></li>
  </ul>
  
  <p>Please can any one suggest me to do the same in <code>asp.net.</code></p>
  
  <p><strong>Note:</strong> <em>I am using Visual Studio 2008 Framework 3.5</em></p>
