[NTG-context] typesetting a url from variabless

Hi, What is the best way of typesetting a url from a variable. For example, if I have \setvariables[test][website=http://www.xyz.com/~abc/first_index.html] how can I print the url. I tried \starttext \goto{\getvariable{test}{website}}[URL(\getvariable{test}{website})] \stoptext but this does not seem to work. Any suggestions? Aditya
