Camel HTTP Producer Proxy Settings

For Camel's HTTP component, put the forward proxy on the producer endpoint that makes the outbound request. In Camel 4.18, a RouteBuilder fragment can use:

from("direct:status")
    .to("https://service.example.net/status"
        + "?proxyHost=proxy.example.net"
        + "&proxyPort=8080"
        + "&proxyAuthScheme=http");

The service URL remains the destination. For a permitted public-API test without proxy authentication, a candidate from the HTTP proxy list can supply the intermediary host and port. proxyHost and proxyPort identify the intermediary; proxyAuthScheme selects the protocol used to connect to it. An HTTP proxy can carry the HTTPS request through a tunnel.

Use property placeholders for deployment-specific values. If proxy authentication is required, the component exposes separate proxyAuthUsername, proxyAuthPassword and authentication-method options. Service authentication uses different options.

This configuration belongs to camel-http. A CXF conduit configures a CXF client; it does not configure an HTTP producer just because the route also contains SOAP-related components. Similarly, a ProducerTemplate dispatches to the endpoint and does not replace that endpoint's transport configuration.

Component-level settings can provide shared defaults. Endpoint-level settings keep a particular route explicit.
