title: why would relative path not work for src in scripts?
body: <p>I am running a simple HTTP server using python. I have an HTML file with the following script tag: </p>
  
  <pre><code>&lt;script src="../../build/react.js"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>The file is present in the right place if the relative URL is followed, but both Chrome and Firefox, look for base/build/react.js instead of base/../../build/react.js. </p>
  
  <p>I remove the relative path, and it works fine as expected. Why are the relative paths not working? </p>
