Hi. Our site is Linux Apache MySQL PHP. We've been trying for over a week now to get this Ajax Uploader working: http://encodable.com/tech/ajaxupload/ It's exactly what we want but we can't get the progress bar to move. We've been in contact with Encodable and they're saying our server is write-caching: "during the upload the script writes to a log file, but on your server it doesn't show up on disk until the upload has finished. On all other servers (save one) that this script has run on, the log file is created right at the beginning of the upload and is readable on disk immediately. So your server is definitely holding the disk-write in RAM until the end of the upload. It may not be something OS-wide; it could be something in Apache itself. On the only other server I've seen this problem, the admin just did an Apache recompile and the problem went away. But my client isn't the server admin so he doesn't know what if anything was changed in the Apache configuration at the same time. It's possible that one of your Apache modules is causing the problem." Our ISP is claiming that no write-caching is going on. So we're really at a loss. We tried a previous uploader: http://www.raditha.com/php/progress.php and we had the same problem. The files would upload but the progress bar wouldn't move. Anyone know about how Apache works in correlation with progress bars. Anyone know of any other good progress bars. An AJAX one would be best as we're already doing a pop up to the upload box so if it was AJAX the upload could remain in that pop up instead of initiating another one.
