Apache Module mod_setenvif

Available Languages:  en  |  ja  |  ko  |  tr 

Description:Allows the setting of environment variables based on characteristics of the request
Status:Base
Module Identifier:setenvif_module
Source File:mod_setenvif.c

Summary

The mod_setenvif module allows you to set environment variables according to whether different aspects of the request match regular expressions you specify. These environment variables can be used by other parts of the server to make decisions about actions to be taken.

The directives are considered in the order they appear in the configuration files. So more complex sequences can be used, such as this example, which sets netscape if the browser is mozilla but not MSIE.

BrowserMatch ^Mozilla netscape
BrowserMatch MSIE !netscape
