How to suppress the security warning when calling a cross domain web service using java script returning jason input and parse the result

Hello,

For one of our project, we are trying call a Rest web service using java script that is returning JSON response.

However, we are using XMLHttpRequest to call the web service but every time we call the webservice we are getting a security pop up.

The application we are using is accessed by many users and it is not possible to change the 'Access Data Sources Across Domain' Check box setting under Miscellaneous in Security settings.

We are using IE 8 or 9.

Can anyone help us on how to suppress this using java script or jquery without changing the setting?

Regards,

Shambo Maitra.
