July 7th Http Error from IE testing

This is the image about failure of Http request in IE.
I didn't find this until Manjula tested it on IE.
The donations list will not refresh itself automatically after a new donation is created.
But this won't happened in Firefox.
So that I guess this is only the problem with browser itself but not from the program.
Initially, I want to solve it by create a function to refresh the list when the donate button is clicked. But the list box and the new donation box is not in the same file. Flex doesn't let me to call the function outside of the file.
And since I haven't find any way to solve this nicely so that I hardcode a button to refresh the list.

Now the project is successfully running on a testing server by Mongrel plugin in rails.
