Perl Http Post over SSL

Hello,

I'm using a tunnel broker for tunneling IPv6 traffic, as my ISP does not support it natively. As of recent i switched from Hurricane Electrics tunnel broker to Sixxs.

Whenever my IP address changes, i have to manually log in and change it. This is a bit cumbersome so i was thinking of devising a Perl script for this.

With my old tunnel broker ( The one from HE), logins were made over basic Http, this made this a lot easier as you could actually see what was being sent. For example, firing up Wireshark showed.

f_user=<username>$clearpass=$f_pass=<md5_password>&redir=&Login=Login

With the tunnel broker from Sixxs logins are made over SSL, so you have no idea of what is being sent. Is there a way to figure out what to pass to POST?

Any suggestions or ideas?
