Answering to last question. Request.UrlReferrer returns an Uri object, so if UrlReferrer has bad format then you get an exception. It seems strange, but some times I have got it. HTTP_REFERER is a string.
回答最后一个问题。 Request.UrlReferrer返回一个Uri对象，因此如果UrlReferrer格式错误，则会出现异常。这看起来很奇怪，但有时我得到了它。 HTTP_REFERER是一个字符串。

Does the Request.ServerVariables[] work in the live situation? It is my understanding that the two are identical.
Request.ServerVariables []是否在实时情况下工作？我的理解是两者是相同的。
Can it be that proxies and/or firewalls (at the server, the client or anywhere inbetween as an ISP) are stripping the referrer?
代理和/或防火墙（在服务器，客户端或ISP之间的任何地方）是否正在剥离引用者？
