Bookmarklet to replace the current domain with localhost:8000

If you, like me, have various projects that do things like OAuth on Twitter or Google or you have a development site that goes to PayPal. So you're doing some Django development on http://localhost:8000/foo and click, for example, to do an OAuth on Twitter with an app you have there. Then Twitter will redirect you back to the live site with which you've set it up. But you're doing local development so you want to go back to http://localhost:8080/... instead.

Add this bookmarklet: to localhost:8000 to your browser Bookmarks toolbar and it does exactly that.

Here's its code in more verbose form:

(function() { 
   a = function(){
     location.href = window.location.href.replace(/http:\/\/[^\/]+\//,
            'http://localhost:8000/')
   };
   if (/Firefox/.test(navigator.userAgent)) { 
     setTimeout(a,0)
   } else {
      a()
   }
 })()
