With a hidden 1Px tall frame, you could put an "onunload" clause such
that a call to your server is initiated. This could then log information
for your use. Typically this would be when a new URL was typed or
bookmarked.
However this method is not foolproof.
A simple example is simply exiting the browser. The unload function is
never called.
For another example, I use Eudora as an
email client and lauching a webpage from the client will cause the last
selected _frame_ (IN netscape) to take on the new page. So in this case,
the hidden frame would not be unloaded and would not trigger the function.
