public void ProcessRequest (HttpContext context) {

    if (context.Request.QueryString["machinenamedisplay"] == null)
        return;
    string connStr = ConfigurationManager.ConnectionStrings["connectionString"].ConnectionString.ToString();

    string machinenamedisplay = "SINGULATION # 2";
    using (SqlConnection conn = new SqlConnection(connStr))
    {
        using (SqlCommand cmd = new SqlCommand("SELECT top 100 CCList from dbo.Obs_PMChkList_1 where machinenamedisplay = @machinenamedisplay", conn))
        {
            cmd.Parameters.Add(new SqlParameter("@machinenamedisplay", machinenamedisplay));
            conn.Open();
            using (SqlDataReader reader = cmd.ExecuteReader(System.Data.CommandBehavior.CloseConnection))
            {
                reader.Read(); context.Response.BinaryWrite((Byte[])reader[reader.GetOrdinal("CClist")]);
                reader.Close();
            }
        }
    }
