<H1 ALIGN="CENTER">Apache module mod_env</h1>
This module is contained in the <code>mod_env.c</code> file, and
is not compiled in by default. It provides for
passing environment variables to CGI/SSI scripts. Is is only available
in Apache 1.1 and later.
<h2>Summary</h2>
This module allows Apache's CGI and SSI environment to inherit
environment variables from the shell which invoked the httpd process.
CERN web-servers are able to do this, so this module is especially
useful to web-admins who wish to migrate from CERN to Apache without
rewriting all their scripts
