curl_exec=page refresh assuming it's the same url

Before you can extract data, you need to tell where you extract it
from, which is the variable that you set 1st curl_exec to. You extract
the key, then you select the same url, post command, and curl_exec the
POST command. Doesn't the 2nd curl_exec reload the page in order to
know where to POST command when it goes to the url thereby refreshing
and changing the key?
