+<p>Just before passing a request to the configured FastCGI server, the core of
+the web server sets a number of environment variables based on details of the
+current request. FastCGI programs often uses these environment variables
+as inputs that determine what underlying scripts they will process, or what
+output they directly produce.</p>
+<p>Examples of noteworthy environment variables are:</p>
+<ul>
+ <li>SCRIPT_NAME</li>
+ <li>SCRIPT_FILENAME</li>
+ <li>REQUEST_URI</li>
+ <li>PATH_INFO</li>
+ <li>PATH_TRANSLATED</li>
+</ul>
+
+<p>This directive allows the environment variables above, or any others of
+interest, to be overridden. This directive is evaluated after the initial
+values for these variables are set, so they can be used as input into both
+the condition expressions and value expressions.</p>
+<p>Parameter syntax:</p>
+<dl>
+<dt>conditional-expression</dt>
+<dd>Specifies an expression that controls whether the environmen variable that
+ follows will be modified. For information on the expression syntax, see
+ the examples that follow or the full specification at the
+ <a href="../expr.html">ap_expr</a> documentation.
+ </dd>
+<dt>environment-variable-name</dt>
+<dd> Specifies the CGI environment variable to change,
+ such as PATH_INFO.</dd>
+<dt>value-expression</dt>
+<dd>Specifies the replacement value for the preceding environment variable. Backreferences, such as "$1",
+can be included from regular expression captures in <var>conditional-expression</var></dd>
+</dl>
+
+<div class="example"><p><code>
+# A basic, unconditional override<br />
+ProxyFCGISetEnvIf "true" PATH_INFO "/example"<br />
+<br />
+# Use an environment variable in the value<br />
+ProxyFCGISetEnvIf "true" PATH_INFO "%{reqenv:SCRIPT_NAME}"<br />
+<br />
+# Use captures in the conditions and backreferences in the replacement<br />
+ProxyFCGISetEnvIf "reqenv('PATH_TRANSLATED') =~ m#(/.*prefix)(\d+)(.*)#" PATH_TRANSLATED "$1$3"<br />
+</code></p></div>
