http to https and back again

[Roman_Totale]

Is there an easy way to force the use of https for specific pages, but to revert to http after exiting that page?

My site has lots of relative navigation links. I have a store page with a php script to force https--but if a user clicks any navigation link, they remain in https. How do I switch them back to http with hard coding all my links?

Thanks

Any ideas using Apache conf? I saw something which suggested setting port based permissions--I'm hesitant to experiment too much on our (only) production server.

If no direct suggestions, recommend any good Apache resources? What I've found on the web is somewhat cryptic.

Thanks
