Synopsis

This module creates variables, the values of which depend on the request header "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 - is equal to the value, assigned by directive ancient_browser_value, if browser is identified as an old browser;
  • $msie - is equal 1, if browser is identified as MSIE with any version;

If you don't need this module add --without-http_browser_module parameter to the ./configure call, at compile time.

Example configuration

Selection of the index file:

modern_browser_value "modern.";
modern_browser msie 5.5;
modern_browser gecko 1.0.0;
modern_browser opera 9.0;
modern_browser safari 413;
modern_browser konqueror 3.0;
index index.${modern_browser}html index.html;

Redirect for the old browsers:

modern_browser msie 5.0;
modern_browser gecko 0.9.1;
