How can I tell java to use a specific outgoing ip interface for a http request?

Question

Does anybody know a quick way to force an outgoing http request to go through a specific (logical) ip address, in java?

I'm thinking of using Apache HTTP client (part of http components), which surely enough has a way to do it, but the API looks not trivial. Has anybody already performed anything similar with it?

Thank you.

Answer 2

use socket.bind(bindpoint) just before socket.connect(endpoint).

bindpoint and endpoint can be InetSocketAddress
