IE behaves strangely on cross-site errors. Some combinations of parameters actually trigger this error.
e.g.
Please try the below URL in IE (Remove the space between http and :)
http ://www.bing.com?a='b'&a=b.jsp&a=b
Can anyone help me n why IE throws error on Bing? I am getting similar error in my applications but not sure why it behaves strangely
