Browser模块

摘要

This module creates variables, the values of which depend on the request header "User-agent":

本模块的变量基于请求头(header)中的"User-agent":

• $modern_browser - is equal to the value, assigned by directive modern_browser_value, if browser is identified as an modern browser;
• $ancient_browser - 当等于指定给modern_browser_value的浏览器时，这个浏览器被认定为新版的浏览器;
• $ancient_browser - is equal to the value, assigned by directive ancient_browser_value, if browser is identified as an old browser;
• $ancient_browser - 当等于指定给ancient_browser_value的浏览器时，这个浏览器被认定为老版的浏览器;
• $msie - is equal 1, if browser is identified as MSIE with any version;
• $msie - 当浏览器为MSIE的任何版本时，这个值等于1;
  If you don't need this module add —without-http_browser_module parameter to the ./configure call, at compile time.

如果不需要这个模块时，在编译的时候加上 —without-http_browser_module.
