How can I authenticate the user

[aliassce]

Hi!

My web site has a product adding and a deleting page. As my server does not allow ASP.NET to write, when adding a product with picture, it ask FTP password through <impersonate> in web.config

And when deleting I need my user to enter FTP password again. But this time page does not ask it as no upload required. My question is how can I make it asked? in other words how can i open FTP username/password dialog manually?

Thanks in advance.
