Editor Control - Error: 'pagetype' is undefined

I am executing a WebRequest. It works well all the time.

But when I put in the editor from the ajax control tool kit and set the content property to the the WebRequest results it works fine from most urls

It works fine on the URL http://www.txlottery.org/export/sites/default/Games/Powerball/Winning_Numbers/powerball.csv

But I get an error from the following URL http://austin.craigslist.org/fuo/3684873639.html
Line: 1 Error: 'pagetype' is undefined

Any ideas???
Thanks
