How to get client domain info?

Question

In a Spring or Restlet web application, how can I get the domain name of the client?

What I can do now is get client IP address only:

String clientIp = getRequest().getClientInfo().getAddress();

However I need to get the domain name of the client.

Mainly because I am making a proxy app which domains from GoDaddy (for example):

• Forward www CNAME to the proxy app.
• Proxy app gets the domain name, say xyz.com, or abc.com and forward it to a specific IP or another domain.

In a general way, I suggest you have a look at the full content of the incoming request. Check the provided headers and see if they contain the data you need.

Uusing Restlet, you can have a look at the request#ClientInfo#UpStreamAddress method. It takes care of forwarding data provided by the request, and returns the client's IP. I don't know what you mean by client's host domain.
