Quick parse_url

Let's say you have an insane URL like a Google Analytics beacon:

var url = 'http://www.google-analytics.com/__utm.gif?utmwv=5.2.4&utms=23&utmn=353317006&utmhn=www.something.something.com&utmt=event&utme=5(monetization_partner*buy_amazon*%2Fseries%2FThe_Millennium_Trilogy_Stieg_Larsson)(1)8(user_type*logged_in)9(119*true)11(1*2)&utmcs=UTF-8&utmsr=2560x1440&utmvp=1103x767&utmsc=24-bit&utmul=en-us&utmje=1&utmfl=10.3%20r183&utmdt=The%20Millennium%20Trilogy%20-%20Small%20Demons&utmhid=1278954452&utmr=0&utmp=%2Fseries%2FThe_Millennium_Trilogy_Stieg_Larsson&utmac=UA-xxxxxxxx-x&utmcc=__utma%3D76481800.571237505.1328141482.1328580205.1328639116.18%3B%2B__utmz%3D76481900.1328141480.1.1.utmcsr%3D(direct)%7Cutmccn%3D(direct)%7Cutmcmd%3D(none)%3B&utmu=6QAAAAAAAAAAAAAQ~';

Now let's say you want to figure it out:

url
  .split(/[?&]/)
  .forEach(function(param){
    console.log( decodeURICompontent(param).replace('=', ': ') ) 
  });

It will look like this:

http://www.google-analytics.com/__utm.gif

utmn: 353317006
utmhn: www.smalldemons.com

utmu: 6QAAAAAAAAAAAAAQ~

So there's that. Enjoy.

Crazy sum*: 6QAAAAAAAAAAAAAQ~

*Some fool with a lot more time than me figured it's a bitmap (not an image!) of functions blah blah blah.

Also, if you wonder if this data could be used by third parties to track you, it appears possibly maybe.

I've changed a couple of numbers in this data, just so I don't get a hater commenting on my stupidity. But hey, haters gun' hate anyway.
