Set cookie jar in Node.js HTTP POST request

I need to send a HTTP POST request using Node.js' Restler.

Now my curl request to set the cookie jar file looks like this:

 curl -c '/tmp/mycookie' -d <data> http://myhost:3000/put

and to read cookies from like this:

 curl -b '/tmp/mycookie' -X POST http://myhost:3000/put1

How I can set mycookie on request object? Should this be request header?
