how to log into a website with a certificate

wergp

I appreciate your assistance.

[u]I need to log into a website with both a user name, password, and a certificate. [/u]

[italic]I have the username, password, and certificate information (using firebug). I have the URL syntax to transmit the username and password.[/italic]

[b]What I can't figure out is which object is best used to transmit the certificate information when I connect to the site.[/b]

Thank you in advance
