Hi All,

I ve upgraded CURL from 7.30 to 7.46.
But here I'm facing one issue in one of the curl command line execution.

In version 7.30 below command works fine for me:
curl -s -k -m 10 -w "\n%{http_code}" http://localhost:8080/logo.gif

Whereas when I upgraded curl to 7.46 same command failed due to CN validation with below error:
curl -vi -s -k -m 10 -w "\n%{http_code}" https://localhost:8443/logo.gif
* Trying 127.0.0.1...

* SSL: certificate subject name 'vm418.abc.com' does not match target host name 'localhost'
* Closing connection 0

Could you please provide me an option so that I can go ahead without CN validation?
Also let me know in which version these changes are introduced.

Regards
Gaurav
