| 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. |
