I am Agalya and I work for Comcast. We are trying to use kamailio as proxy server for our project. 

I have a query regarding the same. We are trying to use REST API calls asynchronously from the config file. 

I see that there is a module "http_async_client" which is used to handle REST services asynchronously. 

Found that libcurl is used to perform these operations. 

My question is:

1) How much time kamailio is taking to send the HTTP request out after TCP port is opened? 

    Is there any time dependency we need to wait on libcurl to send HTTP request out?

    B'coz in opensips I see a delay time and  libcurl is used in-turn. 

    I found kamailio doing similar to opensips and hence am posting this question.

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