title: Changing url for NSMutableURLRequest after its being initialized
body: <p>I am trying to see if there is a way to change the request url once the NSMutableURLRequest is being initialize? I looked into the instance method, but nowhere it indicates that you can change the url. I tried to make a request of "URL" and change it accordingly, but it still points to the old url.</p>
  
  <p>Anyone know how to change this would like to know it.</p>
  
  <p>Thanks.</p>
