On - [removed].hash - Change?

Question

I am using Ajax and hash for navigation.

Is there a way to check if the window.location.hash changed like this?

There are a lot of tricks to deal with History and window.location.hash in IE browsers:

• As original question said, if you go from page a.html#b to a.html#c, and then hit the back button, the browser doesn't know that page has changed. Let me say it with an example: window.location.href will be 'a.html#c', no matter if you are in a.html#b or a.html#c.

• Actually, a.html#b and a.html#c are stored in history only if elements '' and '' exists previously in the page.

• However, if you put an iframe inside a page, navigate from a.html#b to a.html#c in that iframe and then hit the back button, iframe.contentWindow.document.location.href changes as expected.

• If you use 'document.domain=something' in your code, then you can't access to iframe.contentWindow.document.open()' (and many History Managers does that)

I know this isn't a real response, but maybe IE-History notes are useful to somebody.
