   <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>
