[#1]

I have created the web application,now i need to get the document from that specific user.

Here are the sample code.

Redirect the user to QlikView to either a spefic document or to the access point

            if (document.Length>0)

            {

                Response.Redirect("/qvajaxzfc/authenticate.aspx?type=html&try=/qvajaxzfc/opendoc.htm?document=" + document + "&back=/Login.salesforce.com&webticket=" + ticket);

            }

            else

            {

                Response.Redirect("/qvajaxzfc/authenticate.aspx?type=html&try=/qlikview&back=/LoginPage.htm&webticket=" + ticket);

            }

Here,

if have more than one document for that specific user,then how can i form the url?

Can I created for loop and get it?Is this correct or not?

Please let me know as soon as possible?
