<h1 align="center">Environment Variables in Apache</h1>
-<p>Many operating systems provide a facility for storage and
-transmission of information called environment variables. Apache uses
-environment variables in many ways to control operations and to
-communicate with other programs like CGI scripts. This document
-explains some of the ways to use environment variables in Apache.</p>
+<p>The Apache HTTP Server provides a mechanism for storing information
+in named variables that are called <em>environment variables</em>.
+This information can be used to control various operations such as
+logging or access control. The variables are also used as a mechanism
+to communicate with external programs such as CGI scripts. This
+document discusses different ways to manipulate and use these
+variables.</p>
+
+<p>Although these variables are referred to as <em>environment
+variables</em>, they are not the same as the environment variables
+controlled by the underlying operating system. Instead, these
+variables are stored and manipulated in an internal Apache structure.
+They only become actual operating system environment variables when
+they are provided to CGI scripts and Server Side Include scripts. If
+you wish to manipulate the operating system environment under which
+the server itself runs, you must use the standard environment
+manipulation mechanisms provided by your operating system shell.</p>
