    <p><!-- CL 539615 -->
      When executing a CGI process, the <code>PATH_INFO</code> variable is now
      always set to the empty string or a value starting with a <code>/</code> character,
      as required by RFC 3875. It was previously possible for some combinations of
      <a href="/pkg/net/http/cgi#Handler.Root"><code>Handler.Root</code></a>
      and request URL to violate this requirement.
