Be aware that the servlet spec defines the filesize as an signed 32 bit*, so that unless code is written correctly, there will always be a hard limit of 2GB on upload with size information in advance... since one DOS attack is to upload a file of unlimited size (thereby filling your storage) most good upload components will refuse an unbounded upload (which is what anything over 2GB will look like as a result of the servlet spec)
Not sure if this applies to your case, but an FYI for you anyway -Stephen * public int ServletRequest.getContentLength() - returns the length (in bytes) of the content being sent by input stream or -1 if the length is not known (or if the length is greater than 2GB) 2009/10/3 Jim the Standing Bear <standingb...@gmail.com> > thank you for the response, Anuj.
