You probably meant to say that in the start tag of the "body" element there
is a "onbeforeunload" attribute which causes the (one) user agent you have
tested with to execute its value as script code on a certain event.

And what is myCleanUpMethod()? You could have provided this,
but now it really does not matter anymore (see below).

No, it is an intrinsic event handler of the IE(4+) DOM, thus it works only
in this user agent and, BTW, using the handler within HTML context makes the
document invalid or, strictly speaking, no HTML at all:

<http://www.w3.org/TR/html4/interact/scripts.html#h-18.2.3>
Coincidental the ECMAScript implementation that IE supports is JScript,
but that has nothing to do with the UA's DOM. For example, with IE
VBScript code could be executed in the listener.

Nonsense. Java != J(ava)Script. Sun provides a _Java_
Virtual Machine, not a J(ava)Script Virtual Machine.

Revise your Web application, its concept is flawed.
