title: IE 9 BoxModel padding/spacing issue when changing localhost to computername
body: <p>when I run my site on for example: /localhost/Test then the box-model and table borders/padding/spacing etc... looks normal.</p>
  
  <p>Example IE9 Box Model OK localHost: <a href="http://www.flickr.com/photos/cenesam/6243269622/in/photostream" rel="nofollow">http://www.flickr.com/photos/cenesam/6243269622/in/photostream</a></p>
  
  <p>When I run the same test site on: /my computer name/Test then IE9 goes wacky and the box-model increases padding / spacing etc...</p>
  
  <p>Example IE9 BoxModel NOK Computername:

  <p>Does anyone recognize this behaviour and knows how to deal with this?
  I've included 2 sample pictures to show the visual problem. One is with localhost one is with computer name.</p>
  
  <p>Any ideas are much appreciated.
  Thanks,

  <p>Finaly found the answer somewhere on the web.
  Spudley (thank you!) pointed me to the right direction. This meta tag was definitly the answer!!</p>
  
  <p>But what is important that IE NEEDS this tag to be the FIRST one in the Head section. My site uses a theming engine which parses the styles in the head tag and therefore it was not working.</p>
  
  <p>Now I'm overriding this in web.config (webserver section) by:</p>
  
  <pre><code>&lt;httpProtocol&gt;
        &lt;customHeaders&gt;
          &lt;remove name="X-UA-Compatible" /&gt;
          &lt;add name="X-UA-Compatible" value="IE=Edge" /&gt;
        &lt;/customHeaders&gt;
  &lt;/httpProtocol&gt;
  </code></pre>
  
  <p>And now it finaly works again.
  Thank you all for thinking with me!</p>
