Redirect 此网页有一个重定向循环-IIS7

我有一个小网站，我在iFrame中有一个邮件列表联系人表单，一旦提交，我向邮件列表服务注册的回调页面就会被调用，显示在iFrame中，并要求用户检查他们的电子邮件。我注册的页面是。在vertify.html中，我使用“window.parent.document.getElementById（'lightbox4'）.style.display='none'；”关闭包含I框架的lightbox div。这一切都很好，只要用户最初访问，但是如果他们访问，那么调用“window.parent.document.getElementById（'lightbox4'）.style.display='none'；”不起作用，因为这是一个跨域请求

所以，我想没问题，我只需要创建一个重定向规则，将呼叫从www.mydomain.com转换到mydomain.com。但是现在，当我尝试访问www.mydomain.com或mydomain.com时，出现了错误“此网页有重定向循环”。在IIS7中，我有两个绑定，一个用于mydomain.com，另一个用于www.mydomain.com。我的DNS区域有一个mydomain.com的A记录和一个www.mydomain.com的CNAME记录

我在做什么蠢事吗？有什么方法可以调试这个吗？我可以在Firefox中看到，使用Live HTTP headers插件，URL被正确地从www.mydomain.com重定向到mydomain.com，但随后试图继续尝试将mydomain.com重定向到mydomain.com，从而产生了无尽的循环：

and it keeps going until "This webpage has a redirect loop" is displayed

我希望我必须为www.mydomain.com创建一个新的虚拟目录，然后将其重定向到mydomain.com，但这似乎很尴尬
