download a file only one time in vb.net and IIS

Question

I have a link

http://www.example.com/foldername/1.jpg

Is there a way to make this link usable ony once? In other words, if a user downloads this image and anyone tries to download it again (even the same user) the link will not work anymore.

You could use a VB.NET script that reads the image from a protected directory and outputs it to the response stream and then simply delete this image from the directory.

See here how to write an image to the response stream.

Also use the POST method to retrieve the image, [`GET` should be a safe method](http://www.w3.org/Protocols/rfc2616/rfc2616-sec9.html). – SilverlightFox May 06 '15 at 09:19
is there a way without binding the link to a VB.NET project? – User7291 May 06 '15 at 15:31
