[SR-Users] Query with regard to http_client and http_async_client

Hi Giacomo, I have few questions with regard to rest client in kamailio. 1) I see there are two modules in kamailio for rest client. http_client, http_async_client. I hope http_client does the http transfer in synchronous way. http_async_client does the http transfer in asynchronous manner. Correct me if am wrong here. 2) I want to achieve https transfers in async way, so choosing http_async_client. Is there a way that kamailio maintains persistent TCP connection pooling for http transfer. I see there is a "workers" parameter in http_async_client. By increasing this number does it result it more http request's handling? 3) Also, I have some questions regarding documentation for module http_async_client in 5.0 version. In the API exposure, it says "http_async_query(url, route_name)". But the example if I want to use POST, it says "http_async_query("http://example.com/test.php", "{'r_uri':'$rU', 'f_uri':'$fU'}", "HTTP_REPLY");" There is a parameter mismatch between the example and the actual function. If I try to use GET query, kamailio service is starting. But if I try to give the POST query with payload, kamailio service is not started. It says, sctp_core_destroy(): SCTP API not initialized. Also I have noticed that, functions like http_append_header(),http_set_method() are removed in 5.0 version, whereas we have this API's is 4.x versions. Is there some issue with the documentation for 5.0 ? Please let me the know the details for the above queries. Regards, Agalya
