title: Can I set a header with python's SimpleHTTPServer?
body: <p>I'm using <code>SimpleHTTPServer</code> to test some webpages I'm working on.  It works great, however I need to do some cross-domain requests.  That requires setting a <code>Access-Control-Allow-Origin</code> header with the domains the page is allowed to access.</p>
  
  <p>Is there an easy way to set a header with SimpleHTTPServer and serve the original content?  The header would be the same on each request.</p>
