       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.
