<h3>Summary</h3>
<p>This module allows for control of internal environment variables that
are used by various Apache HTTP Server modules. These variables are also
provided to CGI scripts as native system environment variables, and available
for use in SSI pages. Environment variables may be passed from the shell
which invoked the <code class="program"><a href="/programs/httpd.html">httpd</a></code> process. Alternatively,
environment variables may be set or unset within the configuration process.</p>
