The HTTP request is sent right after opening the socket. I've never noticed
a delay between the TCP handshake and the query being sent. Then the
connection is cached and can be reused by subsequent queries to the same
server. Did you observe a different behavior?

2) We can also use PUT service by using http_set_method(PUT)?

$http_req pseudovariable (
http://www.kamailio.org/docs/modules/devel/modules/http_async_client.html#idp23451668)
in this way:

$http_req(method) = "PUT";
