we say curl_easy_perform() for the first time, it will connect to the Server
and then it will fetch the URL of server (as we set option CURLOPT_URL and
Server is expected to reply for this. Is there a time gap between the
connection establishment and sending of CURLOPT_URL or is it like:

1) Once the server get the new connection request,it will accept() it and
make a new socket fd.
2) After this curl will send request to fetch URL and will wait for the
response??

Or steps 1 and 2 are combined in a single step from curl's point of view?
