FileUp Enterprise Edition (FileUpEE) addresses the most complex needs of any secure file transfer application. FileUpEE features the industry’s first-ever file upload resumability for ASP and ASP.NET. Version 5 breaks through the built-in file size limitations of ASP.NET and IIS 6, allowing unlimited uploads. The enterprise edition of FileUp promotes a unique and secure three-tier file transfer architecture where uploads are always kept off vulnerable Web servers and streamed to a safe file store. FileUpEE easily handles multi-gigabyte file transfers (even those in excess of 100 GB), supports Web farms, and functions across firewalls. FileUpEE scales to the most demanding Web sites consisting of numerous server farms and multiple levels of security perimeters.
