title: Search engine's viewpoint of a URL
body: <p>Given below two links which point to the same page with same content. I'm just trying to give this page the right URL. </p>
  
  <p>I can give it one of the following URLs.</p>
  
  <pre><code>http://www.mywebsite.com/help/topic/2001
  </code></pre>
  
  <p>or</p>
  
  <pre><code>http://www.mywebsite.com/help?topic=2001 
  </code></pre>
  
  <p>Now, when a search engine sees this, what's the effect on the page's caching by the engine.
  Do both link have the same effect or one of them can improvise the caching better.</p>
