Hi,
Yes, the problem was with the JnlpDownloadServlet. The browser sends a GET with "if-expired-since" and the
servlet decides the file is not modified because it is the same on the file system. The problem is that I am using some servlet filters to modify the jnlp file and because the behavior of the servelet the jws receives the old jnlp file, with the old dynamic fields.
