Nope, nothing like that unfortunately.

libcurl only establishes connections when you ask for a transfer and there's
no already established one in the pool to reuse. It never establishes any
ahead of time.

But we've discussed similar ideas before and "Offer API to flush the
connection pool" is already in the TODO:

   https://curl.haxx.se/docs/todo.html#Offer_API_to_flush_the_connectio

as well as "Monitor connections in the connection pool":

   https://curl.haxx.se/docs/todo.html#Monitor_connections_in_the_conne

and "Timeout idle connections from the pool":

   https://curl.haxx.se/docs/todo.html#Timeout_idle_connections_from_th

So we can clearly say that there are a lot of ideas on how to improve the
connection caching and the API/controls for that. We mostly lack someone
actually working on that..
