I am using "HttpSendRequestA" function to send HTTP request to HTTP server.HTTP server is having the self-signed certificate which is not installed in client machine. So initially I am getting the below security warning pop up during user authentication in client machine.Here I clicked "yes" and proceed with user authentication. The same function "HttpSendRequestA" is sending the request to server when the client machine is coming out of sleep/hibernate. But i am not getting the security warning pop up here. Please guide us to get the security warning pop up here.

Security warning:

This page requires a secure connection which includes server authentication. The certificate issuer for this site is untrusted or unknown. Do you wish to proceed?
