### Apache Dubbo Component

Java SDK (apache/dubbo)

### Descriptions

Some of our Dubbo projects have to be deployed in two different clusters for certain reasons. To enable mutual calls between these clusters, I want to include the cluster information and the corresponding SOCKS5 proxy address in the URL. This way, when a Dubbo consumer detects a call to a different cluster, it can route the request through the proxy.
