The other web server would pick up the slack. And, just to be clear, this is simply another version of the Holographic Redundancy Fallacy. Unless the web servers have ALL of your applications loaded, they can't failover this way. As to how many applications you can fit on a server, ask your application vendors. The last time I looked at a Microsoft recommendation for a basic data warehousing application, they wanted nine processors for SQL Server (four for database, four for OLAP and one for DTS), plus two web application servers.
