各种浏览器的USERAGENT格式（useragent）

1、用户代理是指浏览器,它的信息包括硬件平台、系统软件、应用软件和用户个人偏好。用户代理的能力和偏好可以认为是元数据或用户代理的硬件和软件的特性和描述；

2、SIP终端系统称为用户代理，即UA(UserAgent)，含用户代理客户机UAC(UserAgentClient)和用户代理服务器UAS(UserAgentserver)两部分；

3、SIP将终端用户称为用户代理,请求方称为用户代理客户，被请求方称为用户代理服务器。UAC负责发起SIP呼叫请求，UAS接收UAC的请求并负责对其做出响应(接受、拒绝或重定向)。

为什么所有浏览器的userAgent都带Mozilla

Mozilla是Netscape的吉祥物，也是Netscape Navigator浏览器使用的内部开发代号。由于Netscape早期的影响力，直到今天，所有浏览器包括IE，向Web服务器报告自己的浏览器标识的 时候，都以 “Mozilla”开头，表明自己是Mozilla兼容的。
