Hello all. Need to setup a secure portion of my site, but I don't need to buy the certificate through Jag, as I won't be doing e-commerce. Just need a secure side of things.

In order to set things up, I'm to use:
http://secure##.nocdirect.com/~username

I'm trying to shunt everything that comes in with that URL to a subdirectory, namely /secure/, and I only want that directory to be secure. Possible? or do I need to have it be a subdomain?

In any case, I'm already rerouting my main domain index page to a subdirectory, using the Apache rewrite rules:
RewriteEngine On
RewriteBase /
RewriteRule ^index.html(.*) /subdirectory/$1

But when I try to use similar logic to reroute the secure server URL to the /secure/ directory, I end up with a 500 error. I'm clearly doing something wrong. Suggestions?
