get document as a string to be parsed by json
 

If I do
window.open("http://myweb.com/?q=test");
then a window is opened with just the json text. (no html formatting
nothing...)
I need to store the json text into a var and then pass that on the the
json parser.
It would be nice if I could to all this without having to open a new
window and loose my old window.
