Hi,

Actually the onload function can be used to call in a standard js function.
Without the need for submitting a form. Also a specific form can be
submitted through the document.FORMNAME or document.forms[x] where x is the
number of the form (0 based indexing I think). You can use the syntax
onUnload="myfunction()" in the body.

According to my book on J/S the onunload function can also live in a
Frameset tag, but I've never got it to work. So it might be a good idea to
avoid it.

Of course if people are logging in to a site then you require them to log
out, it might be a good idea to place some form of checking on whether or
not they have accessed an internal link to prevent the onUnload triggering
at will, namely whenever the document changes...which could be a lot.
