Hi,

Greetings!!

Are there any solution to disable an download link ( auto generate and enable only in 2 hours).
So public users can not download my upload file.

It's very kind of you for discussing with me.
Thanks !

Solution 2

One way to do this could be:

1. have the link created for the file to be downloaded.
2. Get the current time-stamp of server encrypt it and put it in the querystring of download link.
3. whenever someone visit decrypt the qurystring and check with current time.
4. if time elapsed is less then 2 hours let him see the page.
5. if not push him to error page.

+5. A very good solution.

And the reason i choose this kind of solution is that there is no db needed to keep track of stale n fresh links. I.e. All the state of the link is in the link itself.

My link was generate only for an customer, nobody else can using this link for saving the download file. And this link is available in 2 hours.

XML

1) You can add following tag in head of aspx page where (content="5") 5 is second of the interval for refreshing the page.
    <meta http-equiv="refresh" content="5">
   so in your case (2*3600) makes 2 hours refresh.
2) If you are adding download link dynamically so on each refresh toggle by viewstate variable and do remove/add of the hyperlink(<a> </a>) part so downloads gets restricted/allowed.
