I've never tried this out but take a look at the following:

int server_request (request_t *rq, response_t *rs)
{
     http_t *http;
     session_opt_t *so;
     session_t *ss = NULL;

     dbg_return_if (rq == NULL, ~0);
     dbg_return_if (rs == NULL, ~0);

     /* create a session object from HTTP request */
     dbg_err_if ((http = request_get_http(rq)) == NULL);
     dbg_err_if ((so = http_get_session_opt(http)) == NULL);
     dbg_err_if (session_create(so, rq, rs, &ss));

     /* ... do something with rq, rs and ss ... */

     session_free(ss);

     return 0;
err:
     if (ss)
         session_free(ss);
     return ~0;
}

ciao, t.
