682682| `rewriteTarget` | _string_ | RewriteTarget allows users to rewrite the request path before it is sent to<br/>the upstream server (for an HTTP/HTTPS upstream) or mapped to the filesystem<br/>(for a `file:` upstream).<br/>Use the Path to capture segments for reuse within the rewrite target.<br/>Eg: With a Path of `^/baz/(.*)`, a RewriteTarget of `/foo/$1` would rewrite<br/>the request `/baz/abc/123` to `/foo/abc/123` before proxying to the<br/>upstream server. Or if the upstream were `file:///app`, a request for<br/>`/baz/info.html` would return the contents of the file `/app/foo/info.html`. |
683683| `uri` | _string_ | The URI of the upstream server. This may be an HTTP(S) server of a File<br/>based URL. It may include a path, in which case all requests will be served<br/>under that path.<br/>Eg:<br/>- http://localhost:8080<br/>- https://service.localhost<br/>- https://service.localhost/path<br/>- file://host/path<br/>If the URI's path is "/base" and the incoming request was for "/dir",<br/>the upstream request will be for "/base/dir". |
684684| `insecureSkipTLSVerify` | _bool_ | InsecureSkipTLSVerify will skip TLS verification of upstream HTTPS hosts.<br/>This option is insecure and will allow potential Man-In-The-Middle attacks<br/>between OAuth2 Proxy and the upstream server.<br/>Defaults to false. |
