title: javascript:history.back() triggers postback on machine, but not when precompiled
body: <p>On my machine when I test my webapplication (wether in debug or normal) after
  a javascript:history.back() triggers a postback in my app.
  On the other hand it does not occur when i precompile the application.
  Lastly, when I test the same pages on someones elses machine, the postback does not occur at all.</p>
  
  <p>I'm using vs2008, asp.net 2.0 with AutoEventWireup="false"</p>
  
  <p>I checked files with beyond compare, checked metadata.xml but I don't understand why
  on my local it does a postback.</p>
  
  <p>what can be the problem?</p>
