title: Why GWT doesn´t work without ?gwt.codesvr=127.0.0.1:9997
body: <p>I would like to know why GWT doesn´t work without the argument ?gwt.codesvr=127.0.0.1:9997 in the url, I´m redirecting between modules hardcoding the url´s and I have to set this line not to be shown the message: Module XXX Must be (re) compile. </p>
  
  <p>I hope not to have to change this urls in the future when I would change from host mode to we mode...</p>
  
  <p>So is there any better way to link from a module to the other one? I´m doing with:</p>
  
  <pre><code>GWT.getHostPageBaseURL() + "UserRegistration.html ?gwt.codesvr=127.0.0.1:9997 "
  </code></pre>
  
  <p>Thanks in advance.</p>
