Ajax does not work !!!

May 1 2011 1:18 AM

Hi.
I was learning ajax from w3schools.com and copied one of it's examples and paste it to a notepad, then saved it with html extension.
then I changed file names (url that will be retrieved) to one of text files in that folder.
But it creates "Access is denied" error in IE. FireFox does not even execute it.
What's the problem?
Thanks
