Hi All,

i have one link for download,when i clicks on that link,it is asking the password.in the backend i written the code to check for authenticated password.if that password what i have entered is authenticated,that link should get downloaded.i acheieved all this functionality.

now what i want to do is,after the download completed,that page which asking to enter the password has to close.how can i do that?i tried it by using window.close() in password.jsp page.
but it closes all the functionality,even download is also not coming.
