We are experimenting a few issues while uploading files (using FTP) from the WAN, when these files are more than 50MB big. Please note that doing the same on our LAN works very well, even with very big files !
What we observe : we upload a 100MB file from a PC outside our LAN (my own pc at home). The file is totally uploaded, the progress bar behavior is normal till 100%, but finally the applet gets frozen and the forward is never executed. Note that invoking the Cancel button does not work anymore. No particular error message in the Java Console. The point is that this happens when the file is more than 50MB big (i.e. after a certain time). It works perfectly well with a 40MB file. If we try to reload the page containing the JFileUpload applet, we get an IOException Error.
Any idea ?
We would appreciate to make it work properly before purchasing this nice piece of software

Thanks in advance for your help.
