It sounds like your server is timing out and killing the session, but I'm not sure why it would be different on the Solaris system.
I did some experiments with various large files. I first set my session timeout to 600 minutes. I then tested to see how long it took to upload the files from various bandwidth connections. Once I had some stats, I added some code that checks the size of the request and adjusts the timout based on the size. This allows me to keep a reasonable timeout for users that aren't uploading, while giving those who are enough time to do the upload. It seems to work reasonably well, but I still occasionally see uploads that fail. I hope this is helpful Cindy --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
