IE 11 after an error all jquery ajax call ends with "Access is Denied"

Hi all,

I need some help with CORS in IE 11, and it looks after the very first ajax error response from the server, all subsequent calls will be ended with "Access is denied".  The only way is to close the browser and starts a new session.  We have tested for FF and other browser, there are no such problems.

This is really very annoying, you have to close the browser and open a new session, say just for a duplicated key entry error or something similar.  Are there any ways to clear out the error cache after the error response in IE11?  What is the bst way to handle this?

Thanks,

Ning
