ASP.NET URL验证

我们在ASP.NET上有一个自定义REST处理程序,它配置如下,以处理所有传入的请求:

但是,传递一个管道字符,正确编码或根本不编码,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/|产生此错误:

没有用户区代码被执行.这是一个配置选项吗？在IIS 7和VS Studio的2008开发服务器上重现.

Stack Overflow似乎处理这个错误确定,它看起来像一个动态生成的404 MVC页面被渲染 https://stackoverflow.com/%7c.

有任何想法吗？
