Tomcat will stream the data to/from your Servlet. There will be some
small (few K) in memory buffers in the path for efficiency but nothing
approaching the entire file.

The only exception to this case I can think of is when POSTing to a
page that requires FORM authentication. In this case the entire
original request will be saved during the auth process but there is a
fairly low (4K?) default limit on the size of that request.
