推荐答案

加载从的Application_Start 数据库中的值转换为静态词典＆LT;字符串，串＆GT; ，然后检查的BeginRequest 请求的URL，看它是否是在一个重定向字典项是否存在，然后执行 context.Response.RedirectPermanent（值）如果这样做。

Load the values from the database in Application_Start into a static Dictionary<string, string>, then check the requested URL in BeginRequest to see if it's key exists in a redirect dictionary, then do context.Response.RedirectPermanent(value) if it does.
