| <h1 align="CENTER">Module mod_browser</h1> |
| This module is contained in the <code>mod_browser.c</code> |
| 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 <code><a |
| href="mod_setenvif.html">mod_setenvif</a></code> provides the |
| functionality of this module. |
| |
| <h2>Summary</h2> |
| |
| <p>This module allows you to set environment variables based on |
| the name of the browser accessing your document, based on the |
| <code>User-Agent</code> header field. This is especially useful |
| when combined with a conditional HTML language such as <a |
| href="mod_include.html">XSSI</a> or PHP, and can provide for |
| simple browser-based negotiation of HTML features.</p> |

| |
| <p>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 "<code>varname</code>", |
| "<code>!varname</code>" or "<code>varname=value</code>". 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 <code>value</code>. |
| 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.</p> |
| |
| <p>For example:</p> |
| <pre> |
| BrowserMatch ^Mozilla forms jpeg=yes browser=netscape |
| BrowserMatch "^Mozilla/[2-3]" tables agif frames javascript |
| BrowserMatch MSIE !javascript |
| </pre> |

| |
| <p>The <code>BrowserMatchNoCase</code> directive is |
| semantically identical to the <a |
| href="#browsermatch"><code>BrowserMatch</code></a> directive. |
| However, it provides for case-insensitive matching. For |
| example:</p> |
| <pre> |
| BrowserMatchNoCase mac platform=macintosh |
| BrowserMatchNoCase win platform=windows |
| </pre> |
