Help w/Secure pages

My server gave me https://mydomain.secure.powweb.com/ Is there a way to direct
a folder to be secure using a url like this? Say i have a folder called
"secure" how can i make that direct to
https://mydomain.secure.powweb.com/secure/form1.htm and will that screw up my
site structure? Basically, I really only need the form pages to be secure.

Thanks,

Jeremy
