I tested the code in dropbox using the web address.. and it seems to be working.. but I am not able to use the code with the password pop up page i am using...
@Andy, Please see this link
https://dl.dropbox.com/u/25512757/Sand-Box/index.html (note for others who are seeing this link at a later date : it has been taken off. Sorry)
Currently since it is in dropbox server, it is giving a 404 page, but i want it to redirect to a predefined /dragto.html page if it is not leading the user to /Codebox/xyz.html
I understand that you are saying to put your code in the popup page. bur then where should I put the secretIframe, in the resulting page (treasure) ? Please help me..
nb. I am following you in another post in an alternative to make this happen in google app engine.
