title: Append Parameters to my current URL in GWT
body: <p>Im implementing a jQuery widget on my app. I want that on load, the widget starts, and to make this i have to call my url with one parameter.</p>
  
  <p>So, it would be like this MYURL/?param=value</p>
  
  <p>Im doing this right now:</p>
  
  <pre><code>Window.Location.replace(GWT.getHostPageBaseURL()+"?param=value");
  </code></pre>
  
  <p>And works fine, the problem is that reloads the app.</p>
  
  <p>Is there a way to do this without refreshing my webpage?</p>
  
  <p>Thank!</p>
