ASP.NET – Dynamic Download Link Algorithm

I have seen several websites with dynamic download links.

They asked for a valid email address and sent the dynamically created download link To the address.
EX www.mysite.domain / hashvalue1

But how do they do this because the file exists in the domain in a specific location?
www.mysite.domain/download

Are there any instructions for this?

Yes, the Web URL does not have to correspond to the actual file location.
In .NET The easiest way to achieve this is to create an IHttpHandler, which uses a hash-based Response.TransmitFile.

In this case, the URL will be www.mysite.domain/file. ashx? hash = hashvalue1.

If you use Routing (ASP.NET 3.5 SP1) or some kind of URL rewriter, you can get a better URL.
