But the problem is not really related to a servlet just to web architecture.
A strategy is to put an object "token" in the session when you show the form and remove it when the user clicks "upload".
You will then deny uploads if you don't have the token in the session .
Spring forms have support for it (www.springframework.com).

Is there a way to prevent multiple form posts from the same page/user/session using only servlets? I have a page where users can upload files, but I do not want them to keep smashing the upload button if their files are large, and the user becomes impatient.
thank you.
