Hi Daniel,

Thanks for the quick reply. I will check the code and if possible I will
add the getinfo parameter.

The 2nd point about answers my query. Similar to browsers (like firefox and
chrome which support http/2 with HTTPS only), we can configure libcurl,
using this HTTP version.

Regards
Ganesh Nikam
