Currently, libcurl leaves all connections + as they are and first when a connection is iterated over for matching or + reuse purpose it is verified that it is still alive. + + Those connections may get closed by the server side for idleness or they may + get a HTTP/2 ping from the peer to verify that they're still alive. By adding + monitoring of the connections while in the pool, libcurl can detect dead + connections (and close them) better and earlier, and it can handle HTTP/2 + pings to keep such ones alive even when not actively doing transfers on them. 1.16 Try to URL encode given URL -- cgit v1.2.3
