Browser upload timeout

I am using a PHP script which allows the user to upload files through a browser (the script opens an FTP session behind the scenes). The problem is, all browsers (on Mac and PC platforms) often time out after a random amount of time, between five minutes and a couple hours or sometimes not at all. They display a dialog box saying something like the "connection was refused". Usually this means a file can't be uploaded if it's sufficiently large, say, 5-10 megs. The browser appears to be waiting for a response from the server during the upload, which of course doesn't come until the upload is complete. Has anyone found a way to work around this problem? I suspect that this problem will occur no matter what scripting language is used, because it's simply a function of the browser's handling of <INPUT TYPE="FILE"> in a form. I've already tried setting PHP's max_execution_limit in the php.ini file, and I use "ftp_set_option($connection, FTP_TIMEOUT_SEC, 10000);". Thanks for any help! Scott Teresi scott@digispire.com
