Java – create route on camel using domain

I'm running an instance of Apache camel to proxy requests to another server (depending on the URI) The server camel is running many different domains (e.g. app1.server.com, app2.server.com)

Using jetty and http4, I can proxy requests by doing the following:

from("jetty://http://app.server.com:8080/app1?matchOnUriPrefix=true").to("http4://app1host:8080?bridgeEndpoint=true&throwExceptionOnFailure=false");

from("jetty://http://app.server.com:8080/app2?matchOnUriPrefix=true").to("http4://app2host:8080?bridgeEndpoint=true&throwExceptionOnFailure=false");

Is there any way to create a route based on the domain name? Something like this:

from("jetty://http://app1.server.com:8080?matchOnUriPrefix=true").to("http4://app1host:8080?bridgeEndpoint=true&throwExceptionOnFailure=false");

from("jetty://http://app2.server.com:8080?matchOnUriPrefix=true").to("http4://app2host:8080?bridgeEndpoint=true&throwExceptionOnFailure=false");

thank you very much.

Solution

You can create a content-based router like this（ http://camel.apache.org/content-based-router.html )

from("jetty://http://0.0.0.0:8080")
    .choice()
        .when(header("host").contains("app1.server.com"))
            .log("app1.server.com").to(...)
        .when(header("host").contains("app2.server.com"))
            .log("app2.server.com").to(...);
