Apache module mod_browser

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.

Directives

• BrowserMatch
• BrowserMatchNoCase

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

BrowserMatchNoCase

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
