Hi,
I make http request/response (and upload of file too ) with casablanca in a COM STA object. (an outlook addin)
it seems to block the software ( I cannot do something else and must wait,it freezes).

the following code is in a send(...) function in my STA COM object:

client.request(requete).then([this](task<http_response> responseTask)
{
http_response response;

                try
                {

                    response = responseTask.get();
                }
                catch (const http_exception &e)
                ...

does casablanca run well and parallel in a COM STA object ? shall I do something more to run my tasks parallel ?

or should I use atlserver library(or winhttp) and win32 instead of casablanca for http requests and multithreading(win32) in my COM object ?
(I will still use casablanca to parse the json in the responses.)
