【问题描述】：
比较不同浏览器的以下用户代理字符串：
IE8
Mozilla/4.0（兼容；MSIE 8.0；Windows NT 6.1；WOW64；Trident/4.0；SLCC2；.NET CLR 2.0.50727；.NET CLR 3.5.30729；.NET CLR 3.0。 30729；媒体中心 PC 6.0；.NET4.0C；InfoPath.3；.NET4.0E)
Firefox 3
Mozilla/5.0（Windows；U；Windows NT 6.1；en-US；rv:1.9.2.16）Gecko/20110319 Firefox/3.6.16
Chrome 10
Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.204 Safari/534.16
我看到 Firefox 和 Chrome 在显示浏览器名称方面是一致的（在上面的示例中以粗体显示），但是 IE 在字符串中的完全不同的位置显示它... HttpBrowserCapabilitiesBase 类如何解析这个细绳？以及如何使用此解析器（或自定义解析器）来处理 Wurfl 存储库？（例如，在 Win mobile 上使用时，我无法在存储库中的任何位置找到 User_agent="IE6"）
这些是来自 .NET HttpBrowserCapabilitiesBase 类的 Request 对象中的变量。
