title: System.IO.File.Exists() returns false
body: <p>I have a page where I need to display an image which is stored on the server. To find that image, I use the following code:</p>
  
  <pre><code> if (System.IO.File.Exists(Server.MapPath(filepath)))
  </code></pre>
  
  <p>When I use this, I get a proper result as the file is present.</p>
  
  <p>But when I give an absolute path like below:</p>
  
  <pre><code> if (System.IO.File.Exists("http://myserever.address/filepath"))
  </code></pre>
  
  <p>It returns false.</p>
  
  <p>The file is physically present there, but I don't know why it's not found.</p>
