Redundant IIS Web Servers using SSL

Hi,
I am trying to deploy our companies product to an ASP and I want to have redundant webservers that front Weblogic app servers using SSL for our internet clients. We will be giving our clients there own url i.e. company1.xycorp.com, company2.xyzcorp.com .... How would I accomplish this with multiple web servers? Would each web server have a cert and the same web site configuration. Is this the common way to accomplish this. Also, I was thinking of buying a load balancing appliance to distrubute the load to each web server, is this common? Any help is appreciated.

There's not enough information to provide a design, but the ways to accomplish what you want are many.
If you are considering a front end load balancer, consider one that does SSL as this will ease your certificate management issues however, you can only have one website name per certificate (common name). If your your customers are commerical clients who want internet users to browse their sites using SSL and not get any scary messages about the website not matching the URL, then you will need a unique certificate and IP for each site. Also, be sure that you use some equivalent of "sticky sessions" so that once the SSL handshake is negotiated, your client isnt "load balanced" to another server. You can also find application aware devices that allow you to route to particular websites based on the URL. That may be useful here as well. Otherwise, you can use NLB which of course is already pid for with the server and will work just fine for load balancing.
