【问题描述】：

我有数千个links，需要使用301 Permanent Redirect 将redirect 转换为new URL。我在数据库表中有所有这些urls。我想知道应该在哪里加载这些 URL（仅一次）。并可用于301永久重定向。

示例网址：

*RequestForURL*                                                             *301Redirect*

    why-me/onboard-experience/types-of-me/->    /why-me/onboard-experience/

我正在使用 VS 2013 Framework 4.0

注意： 数据只能在 Session 中或在第一次应用请求期间加载一次。

【解决方案1】：

将Application_Start中的数据库中的值加载到静态Dictionary<string, string>中，然后检查BeginRequest中请求的URL以查看它的键是否存在于重定向字典中，如果存在则执行context.Response.RedirectPermanent(value)。
