<p>Ce module permet de contrler les variables d'environnement
internes utilises par divers modules du serveur HTTP Apache. Ces
variables sont aussi accessibles aux scripts CGI en tant que
variables d'environnement systme natives, et disponibles dans les
pages SSI. Les variables d'environnement peuvent
tre transmises depuis le shell qui a lanc le processus
<code class="program"><a href="../programs/httpd.html">httpd</a></code>. Elles peuvent galement tre dfinies ou
supprimes au cours du processus de configuration.</p>
