Https protocol... forcing for a controller

I need to secure a portion of my applicaction using SSL/https. I have
downloaded ssl_requirement which works fine if there are a few
discrete methods in a controller. However, one of my controllers uses
a display/UI plugin that has many, many methods and I would like to be
able to just say that this controller must always use https…

Is there any straight-forward way or parameter to orce this one
controller to use SSL always? Having to redirect every call (which is
what ssl_requirement does) would be very slow and cumbersome.

Thanks…jon
