您也可以做类似 HTTP：// WWW当后提交.untiny.me / 。基本上，发送一个HTTP请求，并捕获HTTP 301响应。然后，您可以检查你正在被重定向到URL和拒绝/允许根据您的策略。

You could also do something like http://www.untiny.me/ when a post is submitted. Basically, send an HTTP request and capture the "HTTP 301" response. You can then examine the URL you're being redirected to and deny/allow based on your policy.

例如：

C:\>wget -O NUL http://tiny.pl/htk
