XUpload

XUpload is an advanced progress bar indicator for web based file uploads written on Perl. XUpload lets you to accept file uploads on your website and shows upload progress bar which is showing upload progress in real-time. Upload progress bar could be shown in popup window or right on the upload page. It also shows upload progress in percents, upload speed (kb/s), elapsed and remaining time, size of uploading files (useful when uploading multiple files). You can stop file upload process by just pressing stop button. If file transfer will fail during upload process - error message will be shown.
XUpload will work on any hosting, virtual/shared or dedicated and on all platforms driven by Apache Web Server - Linux or Windows.
There will be no problem with integration of XUpload with your login system because XUpload will "pass" all parameters through itself. In other words - it's absolutely "transparent" to any environment and could be integrated with any framework: PHP, JSP, etc. The only one thing needed - Apache web server and Perl installed. No Flash, AJAX or Java needed - pure Perl and DHTML is used.
