How to log the page parameters for every request

Hallo everyone,

I have a problem, which I am fiddling around since some time now.
I would like to log the URL parameters from a Vaadin application withing a servlet filter.
The problem here is, that the servlet filter does only have the resulting URL which is that shown in the browser after all handlers have been processed.
I need somehow to get the final URL in a servlet filter or some instance, where I can process every request and log the details of the URL.
How and where in the Vaadin framework would I do this?

THanx in advance.

Beste regards,
