ASP.NET URL验证

我们在ASP.NET上有一个定制的REST处理程序,它被配置为处理所有传入的请求：

<add path="*" verb="*" type="REST.RESTProtocolHandler"/>

但是,传递一个管道字符,正确的编码或根本不会触发一个似乎来自ASP.NET内部的验证错误.

访问http://localhost:8080/%7c或http://localhost:8080/|会导致此错误：

[ArgumentException: Illegal characters in path.]

没有用户地址代码被执行.这是一个配置选项吗？转载于IIS 7& VS Studio的2008 devel服务器.

堆栈溢出似乎处理这个错误OK,它看起来像一个动态生成的404 MVC页面渲染为https://stackoverflow.com/%7c.

有任何想法吗？

解决方法

protected void Application_Error(Object sender,EventArgs e)
{
    Exception ex = Server.GetLastError();
    //do whatever you want with that exception
    //or get the url from the context,reformat and redirect
}
