jmkeyes/httpclient-proxy-protocol

A HttpClient ConnectionSocketFactory that injects a PROXY protocol header on every established connection.

Apache HttpClient PROXY Protocol Shim

Provides a ConnectionSocketFactory that injects a PROXY protocol header (v1) when opening a connection.

Getting Started

Add the dependency:

<dependencies>
    <dependency>
        <groupId>io.github.jmkeyes</groupId>
        <artifactId>httpclient-proxy-protocol</artifactId>
        <version>1.0.0</version>
    </dependency>
</dependencies>

Register the ProxyProtocolConnectionSocketFactory:

Registry<ConnectionSocketFactory> registry = RegistryBuilder.<ConnectionSocketFactory>create()
        .register("http", new ProxyProtocolConnectionSocketFactory(new PlainConnectionSocketFactory())
        .register("https", new ProxyProtocolConnectionSocketFactory(new SSLConnectionSocketFactory(sslContext)));
        .build();

PoolingHttpClientConnectionManager connectionManager = new PoolingHttpCLientConnectionManager(registry);

HttpClient client = HttpClients.custom()
        .setConnectionManager(connectionManager)
        .build();

Now whenever client creates a new connection it will send the PROXY header automatically.
