CURLINFO_APPCONNECT_TIME explained

Name

CURLINFO_APPCONNECT_TIME - time until the SSL/SSH handshake is completed

Synopsis

 #include <curl/curl.h>   CURLcode curl_easy_getinfo(CURL *handle, CURLINFO_APPCONNECT_TIME,   double *timep);

Description

Pass a pointer to a double to receive the time, in seconds, it took from the start until the SSL/SSH connect/handshake to the remote host was completed. This time is most often close to the CURLINFO_PRETRANSFER_TIME time, except for cases such as HTTP multiplexing where the pretransfer time can be delayed due to waits in line for the stream and more.

When a redirect is followed, the time from each request is added together.

See also the TIMES overview in the curl_easy_getinfo man page.

Example
