Links are amazing things.

They point to web pages or images.

But imagine the flexibility if you could easily create links that exist for a limited time only, or that exist for a limited time after first use. A link that limits the number of IP addresses that can use it. A link that once used, invalidates another set of links.

  • Find out if someone read an Email message or visited a web page.
  • Distribute software or documents with a high degree of security.
  • Offer and track special discounts or offers to customers.

OneTimeDownload-5M is the ideal link manager for ASP.NET. And like all of the Universal .NET package - you not only get this advanced functionality, you get the source code to see how it's done.


  • Create unlimited unique links, each with a specified expiration date.
  • Specify time a link remains active after first use.
  • Links are associated with a URL, file path, and optional description or user defined data.
  • Links can define a group. Use of one link invalidates the others in the group.
  • Links are highly secure. 128 bit link identifiers virtually eliminate the possibility of guessing a link.
  • Specify IP limits to increase security. Once a link is used by the specified number of IP addresses, only those IP addresses can continue to access it.
  • Document/file download links. Supports direct download for common file types. Easy customization to support additional file types.
