 ## TLS请求设置
 
 如果转发的目标节点启用了TLS，可以通过设置`forwarder.nodes.tls`来建立TLS连接。

 ### Rewrite URL Path
 
-Define URL path rewriting rules by setting the `http.rewrite` option. `rewrite.match` specifies the path matching mode (supports regular expression), and `rewrite.replacement` sets the path replacement content.

 ## TLS Settings
 
 If the forwarding target node has TLS enabled, you can establish a TLS connection by setting `forwarder.nodes.tls`.
