     # Method Summary
     #   Before a request gets sent out we need to make sure 
     #   it's formatted correctly and contains the right 
     #   info. We are adding the CSRF tokens in the header
     #   so our POST request work and making sure any
     #   namespaced attributes are working so the server is
     #   happy. If we are using other AJAX request to post 
     #   date we will have to add something for jQuery.
