I have a site which manages the creation of Second Life users for a particular island. Users will create a Second Life account through the site's RegAPI. However, their account information are not given to user, but instead store within a database. The requirement is that the user will log onto our site first (using our own authentication) and we'll automatically log their avatar into Second Life.
How do I send a request to log into Second Life from our site, and obtain a session id which we then pass to the user's viewer (through the secondlife::// protocol)
