<tr><th><ahref="directive-dict.html#Compatibility">Compatibility:</a></th><td>Directive supported in 2.4.18 and later. 2.4.17 acted
as if 'QualifyRedirectURL ON' was configured.</td></tr>
</table>
<p>This directive controls whether the server will ensure that the
REDIRECT_URL environment variable is fully qualified. By default,
the variable contains the verbatim URL requested by the client,
such as "/index.html". With <codeclass="directive"><ahref="#qualifyredirecturl on">QualifyRedirectURL ON</a></code>, the same request would result in a
value such as "http://www.example.com/index.html".</p>
<p>Even without this directive set, when a request is issued against a
fully qualified URL, REDIRECT_URL will remain fully qualified.
