title: Why are Github project document page urls case sensitive? What are the negative effects?
body: <p>I Just uploaded a sample index.html page for my github project repo gh-pages branch. However it seems the url used to access the documentation is case sensitive. The correct url is as follows,</p>
  
  <p><a href="http://harindaka.github.com/ASPTokenInput/" rel="noreferrer">http://harindaka.github.com/ASPTokenInput/</a></p>
  
  <p>However if I use the same url in lowercase github displays a page not found message. i.e.</p>
  
  <p><a href="http://harindaka.github.com/asptokeninput/" rel="noreferrer">http://harindaka.github.com/asptokeninput/</a></p>
  
  <ol>
  <li>Why is the URL case sensitive?</li>
  <li>Will this negatively affect search engine visibility and browser caching etc.?</li>
  <li>What are the disadvantages/advantages of a case sensitive url approach?</li>
  <li>Does this mean some other project can have the same name and url in a different case on github? (shivers :-O)</li>
  </ol>
  
  <p>Thanks in advance.</p>
