Comments:
It appears that this JavaScript excerpt is not reliable, as the definition of the A tag and the onClick attribute has it that the HREF attribute will be followed if the onClick JavaScript excerpt returns true.

So if you have

<a href="default.html" onClick="history.go(-1)">, the
history.go(-1) will return true,
causing the default.html to be
jumped to.

IE appears not to do this, either
due to asynchronously executing the default.html jump before the history.go(-1), or through history.go(-1) returning false.. the return value of history.go() appears to be undefined in the JavaScript specs I've seen.

The proper code here should be

<a href="default.html" onClick="history.go(-1); return false">
