SSL

OK, I've got Pier running behind Apache, responding to both http and https via OpenSSL, but I'm running into a problem. All the generated url's are fully qualified, so though it'll respond to SSL, as soon as I click something I'm thrown back into standard http. I figured this had to be common, but after digging around in the archives for a while, I've found nothing that panned out. Now, I can see that Server Protocol is set to http in the site configuration. Can a site only run in one mode or the other? What if I only want two pages to be secure for a checkout but the rest of the site unsecured? I don't know, maybe it's just late and I'm making a simple mistake, but I'm stumped, anyone know how to deal with this? -- Ramon Leon
