I use MultiPartRequest to upload csv file, upload is ok when the size of the file is less than 15ko, but when I try to upload a file more than 15ko I have an Error 500, Error in server external filter.
Are you using the O'Rielly package or custom code? If you're using the latter, I believe that there is a default limit specified in the source (if you don't create a new request with arguments indicating otherwise). Otherwise, it could be a server config that prevents really large uploads (a security features preventing denial of service attacks). The only other thing that comes to mind is that the server/servlet may be busy uploading data when the browser/serlvet tries to redirect. Therefore, the request is delayed and the browser times out. This is a bit of a long shot, though, and I'd look into the others first. Hope this helps. Sean
