+When you turn on **Preserve original path and query string**, Gateway will append the original path and query string to the redirected URL. Paths and queries in the redirect URL take precedence. For example, if the original URL is `example.com/path/to/page?querystring=X` and the redirect URL is `cloudflare.com/redirect-path?querystring=Y`, Gateway will redirect requests to:

For example, if the original URL is `example.com/path/to/page?querystring=X&k=1` and the redirect URL is `cloudflare.com/redirect-path?querystring=Y`, Gateway will redirect requests to:

+```txt "cloudflare.com/redirect-path" "?querystring=Y" ins="&[email protected]"
