string strUrl = "SelectReport.aspx";

Session["browser"] = true;

HttpCookie cookieClientCode = new HttpCookie("cc", strClientCode);cookieClientCode.Expires = DateTime.Now.AddYears( 1 );

Response.Cookies.Add(cookieClientCode);

 

string strRefreshHeader = string.Format("0; URL={0}", strUrl);

Response.AppendHeader("Refresh", strRefreshHeader);

 It's setting a session variable and a cookie probably for use in later code, possibly the SelectReport.aspx page. Then it's setting a header in the response stream to redirect to SelectReport.aspx as soon as the page loads on the client.
