WebForm页面加载后，多次使用清缓存代码，IE无法加载页面
在Page_Load里使用了如下代码122次后，页面就无法加载了。而，121次却可以，请高人指点。
HttpContext.Current.Response.Buffer = true;
HttpContext.Current.Response.Expires = 0;
HttpContext.Current.Response.ExpiresAbsolute = DateTime.Now.AddSeconds(-1); //DateTime.Now.AddDays(-1);
HttpContext.Current.Response.AddHeader("pragma", "no-cache");
HttpContext.Current.Response.AddHeader("cache-control ", "private");
HttpContext.Current.Response.CacheControl = "no-cache";
HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
HttpContext.Current.Response.Cache.SetAllowResponseInBrowserHistory(true);
