This value indicates whether SSL support shall be enabled. It directs AuctionWorx to load pages with SSL when necessary and without SSL when it would provide no security benefit.
Before this value is set to “true” the unsecure and secure URL’s must be properly defined in the admin control panel. If they are not, the systems efforts to secure pages via SSL may actually make the secure admin control panel unreachable.
To enable SSL, you would change the highlighted value below to "true"
<add key="EnableSSL" value="false" />
