To start building a WebSocket proxy, you need to create a new Java project in your Integrated Development Environment (IDE).

First, open your IDE and create a new Java project. This will give you a clean slate to work with.

Set up the project with the necessary dependencies, including the WebSocket server library you plan to use. This will ensure that your project has all the tools it needs to function properly.

Here's a list of the dependencies you'll need to set up:

To configure the server, you need to specify the target WebSocket server's URI and port. This is done by modifying the WebSocketProxy class. You can do this by adding a static variable to hold the target server's URI and port, as shown below:

```java

public class WebSocketProxy {

private static final String TARGETSERVERURI = "ws://target-server.com:8080/websocket";

```

The target server's URI should be in the format "ws://target-server.com:port/websocket". You can replace "ws://target-server.com" with the actual URI of your target server.

Configuring Client Transports is a crucial step in setting up a Java WebSocket proxy. You can configure a ClientTransport using the ClientConnectionSettings class, which is not possible through config files but only by code.

To do this, you'll need to use the ClientConnectionSettings.withTransport method to configure a transport, then pass the resulting ClientConnectionSettings to the ConnectionPoolSettings.withConnectionSettings method.

Here's an example of how to configure a Web Socket transport:

ClientTransportClientTransport can be configured in the ClientConnectionSettingsClientConnectionSettings. You can customize host name resolution using ClientTransport.withCustomResolverClientTransport.withCustomResolver.

This allows you to implement a custom resolution function, which can be used to resolve hostnames to InetSocketAddress. You can use Apache Pekko's Async DNS Resolution as the backend for this function.

Potential use cases for custom host name resolution include querying SRV DNS records that contain both address and port for a service, or implementing a load balancing algorithm to select a different target address for each connection.

By following these steps, you can configure client transports to suit your specific needs and improve the performance and reliability of your Java WebSocket proxy.
