So I'm looking to implement SSL into my site but as most of you know, a drop in adsense revenue is possible. So the only benefit I'd like to get out of SSL is the security. I'm basically looking to force all my login and registration forms over SSL. I've seen other forums do it so it's definitely possible. They basically iframed a seperate login/register form into their web pages. Usually something like 'https://auth.forum.com'. Could I get some more explanation on what the best way would be to approach this?
