description: |
    Requests forwarded by ReverseProxy include the raw query parameters from
    the inbound request, including unparseable parameters rejected by net/http.
    This could permit query parameter smuggling when a Go proxy forwards a
    parameter with an unparseable value.

    After fix, ReverseProxy sanitizes the query parameters in the forwarded
    query when the outbound request's Form field is set after the ReverseProxy.
    Director function returns, indicating that the proxy has parsed the query
    parameters. Proxies which do not parse query parameters continue to forward
    the original query parameters unchanged.
