[FX.php List] [OFF] https per page?

[Joel Shapiro]

Hi all

What's the best way to use an SSL cert on only certain pages (e.g.  
login & checkout)?

I'd like to keep my links 'local' (e.g. detail.php?id=123 instead of http://server/detail.php?id=123) 
  but have certain pages always use https.

Is there an easy setup in Apache or something, or do I need to check  
at the top of the PHP and redirect if it's the wrong protocol?

OS X Server 10.6

TIA,
