    For the web application use DNS instead like myapp.domain.com and assign two IPs (A records) to it. It will be working as round-robin load balancing and when one server will crash, it will direct you to the another one. This is the simplest yet quite effective method providing some extra availability, assuming you have session in external database or you are using clustered storage.
    Also, when one of your webservers is not available, you can dynamically remove it’s IP from the DNS, and this DNS A record should have 300 seconds TTL.
