Keep-Alive HTTPS connection

Hello!

How can i keep alive of HTTPS connection in new API?
My variant is using one

http = CreateObject("roUrlTransfer")

object in all application. And just call periodically

http.AsyncPostFromString(request)

when it is needed.

But first of all i have no idea how to use it with multithreading (multiple area of visibility)…

What do you think?

Thanks!
