Counterclockwise HTTP REPL

In Eclipse+Counterclockwise, when I want to connect to REPL, the dialog tells me I can use nREPL over HTTP:

How to set this up? Is this somehow connected to drawbridge? I haven't been able to make these work together, although lein repl :connect http://my.url/repl worked for me.

For clarity, why this is useful compared to classic REPL: classic REPL works for localhost only. You can bridge it through SSH port tunnelling, but this - REPL over HTTP - is a viable alternative for remote, "live" servers.

Just for completeness, the server side:
