Apache HTTP Server Version 1.3
Module mod_browser
This module is contained in the mod_browser.c file, and is compiled in by
default. It provides for setting environment variables based on the browser. This module is
part of Apache 1.2.* only. From Apache 1.3 onwards
mod_setenvif provides the
functionality of this module.
Summary
This module allows you to set environment variables based on the name of the browser
accessing your document, based on the User-Agent header field. This is especially
useful when combined with a conditional HTML language such as
XSSI or PHP, and can provide for
simple browser-based negotiation of HTML features.

Compatibility:
Apache 1.2 and above
The BrowserMatch directive defines environment variables based on the User-Agent header.
The first argument should be a POSIX.2 extended regular expression (similar to an egrep-style
regex). The rest of the arguments give names of variables to set. These take the form of
either "varname", "!varname" or "varname=value".
In the first form, the value will be set to "1". The second will remove the given
variable if already defined, and the third will set the variable to the value given by value.
If a User-Agent string matches more than one entry, they will be merged. Entries are processed
in the order they appear, and later entries can override earlier ones.
For example:
BrowserMatch ^Mozilla forms jpeg=yes browser=netscape
BrowserMatch "^Mozilla/[2-3]" tables agif frames javascript
BrowserMatch MSIE !javascript
Syntax:
BrowserMatchNoCase regex attr1 attr2...
Context:

Status:

Module:

Compatibility:
Apache 1.2 and above
The BrowserMatchNoCase directive is semantically identical to the
BrowserMatch directive. However, it provides for
case-insensitive matching. For example:
BrowserMatchNoCase mac platform=macintosh
BrowserMatchNoCase win platform=windows
