301从asp.net中的数据库重定向动态URL

我有成千上万的链接需要重定向到新的网址使用301永久重定向。我在数据库表中有所有这些URL。我想知道应该在哪里这些网址应该只加载一次。并可用于301永久重定向

示例URL：

我正在使用VS 2013 Framework 4.0

注意：数据必须只加载一次到会话中或在第一次应用程序请求期间加载。

将应用程序启动时数据库中的值加载到静态字典中，然后在BeginRequest中检查请求的URL以查看其密钥是否存在于重定向字典中，如果存在，则执行context.Response.RedirectPermanentvalue

*RequestForURL*                                                             *301Redirect*
