JSP page clears forward history in IE

I have a hosted JSP page. When I visit another page from jsp (lets say google.com) and hit the browser's back-button my jsp page reloads but instantly clears the forward history (the forw开发者_如何学运维ard button grays out and I cannot use history to access google.com). I was not aware of any functions in either java or javascript that could clear a browsers forward history. This behavior only happens in IE and not firefox or chrome.

Does anyone have any hint as to what could be possibly be happening in a jsp page that causes the forward history to clear on IE, but not firefox and chrome?
