interesting to create a Servlet Filter that would intercept multi-part
requests on their way to the CFM Servlet. This filter could limit the
size of an upload based on a session variable and more interestingly
could also update a session variable on the progress of the upload.
When the upload is finished it would just pass the request off to the
CFM Servlet and things should work normally from there.
