+---------------------------------------------------------------------------
+TAG: url_rewrite_program
+Specify the location of the executable for the URL rewriter.
+Since they can perform almost any function there isn't one included.
+
+For each requested URL rewriter will receive on line with the format
+
+URL <SP> client_ip "/" fqdn <SP> user <SP> method [<SP> kvpairs]<NL>
+
+In the future, the rewriter interface will be extended with
+key=value pairs ("kvpairs" shown above).  Rewriter programs
+should be prepared to receive and possibly ignore additional
+whitespace-separated tokens on each input line.
+
+And the rewriter may return a rewritten URL. The other components of
+the request line does not need to be returned (ignored if they are).
+
+The rewriter can also indicate that a client-side redirect should
+be performed to the new URL. This is done by prefixing the returned
+URL with "301:" (moved permanently) or 302: (moved temporarily).
+
+By default, a URL rewriter is not used.
