This allows the store owner to manage their admin panel's session expiration, as well as the customer's session expiration via Admin>Configuration>Sessions. If you have a problem where the customer session will not expire and/or the admin panel session expires every few days, then this addon will fix it. This contribution's application-level session expiration directives will override those of the server-side. I made this for BootStrap Edge, but it will likely work with other versions of osC. I only tested it on BS Edge. 1 database change, and 2 easy file changes. This is the full package. (includes screenshot)
