Depends on whether or not the load balancer does SSL termination? if the load balancer does not do SSL termination you need a certificate on both the load balancer and the websites, if the load balancer does SSL termination you do not need a certificate on the webservers. It also affects your code if you try to generate full urls to something if the load balancer is doing SSL termination or not. Other than that, just configure the sites as you would normally in Episerver, just point them to https://yoursite.com and mark it https scheme and so on and you should be good to go.
I would suggest the load balancer does the http to https redirects for all requests, just the easiest to maintain imho.
Common pitfalls in load balanced environments:
And thank you for your answer!
I'm a developer so I can't say I know a whole lot about load balancers. However, there are people here at work that do so I'll talk to them if necessary.
The site's already load balanced between two servers so everything should be set up. Apart from the certificate and HTTPS that is.
Can anyone point me in the right direction (forum posts, blogs, articles and so forth) on how to enable SSL on a load balanced site?
Obviously you need a valid certificate and some redirect rules in web.config, but apart from that? Are there any potential pitfalls? What settings do I need in admin (Manage websites)? Is the procedure the same for a load balanced site as for a single server site?
