title: how to make full page refresh
body: <p>i have an asp.net application on C#,
  and i have a page to change the profile picture, 
  But when i change the picture, the new picture doesn't appear until i press ctrl+f5, 
  so i need to do some process to clear cache and "full reload" the page.</p>
  
  <p>I tried the following code but it didn't make any thing</p>
  
  <pre><code>Response.Cache.SetCacheability(HttpCacheability.NoCache);
  Response.Cache.SetExpires(DateTime.Now.AddMinutes(-30));
  Response.Redirect(Request.RawUrl);
  </code></pre>
  
  <p>So i'm searching for another way to solve the problem</p>
