On-Click transfer to Report Viewer

I am currently trying to generate statements on the fly for members of my website.  When the user selects a month from the dropdown menu and click "generate", it will create a pdf statement for them to view and download.  I will be using a "Server.Transfer" to send my info to the report page.  I have 4 parameters I will be passing along; billmonth, memberid, sitecode, and companycode.

Here is my c# for the page the member will be clicking for the statement.

        protected void btn_genbill_Click(object sender, EventArgs e)
        {
            Session["sitecode"] = ConfigurationManager.AppSettings["sitecode"].ToString();
            Session["memberid"].ToString();
            Server.Transfer("billing.aspx?Report=Form9854&billmonth=" + ddl_1099.SelectedValue);
            
        }

Here is the c# for the billing page (I got this code from http://msdn.microsoft.com/en-us/library/microsoft.reporting.webforms.ireportservercredentials%28v=vs.90%29.aspx but haven't filled it out yet since I have no clue on this sort of stuff.)

Does your report server expects authentication details ? if so , above is the sample to pass the credential from your web form to your report server.

"MyReportServerCredentials" is a separate class which should used inside the asps which is going to  call/transfer the request to report server.

Hope this helps.
