internal static string CreateOutputCachedItemKey

 

                    /* handle all params case (VaryByParams[*] = true) */
                    if (getAllParams && col.Count > 0) {
                        a = col.AllKeys;
                        for (i = a.Length - 1; i >= 0; i--) {
                            if (a[i] != null)
                                a[i] = CultureInfo.InvariantCulture.TextInfo.ToLower(a[i]);
                        }
 
                        Array.Sort(a, InvariantComparer.Default);
                    }

不明白, 为什么要 ToLower ?!
