failover

I have one web server and two WAN connections (1 cable, 1 DSL). DNS is run offsite, and points to the IP address assigned by one of the ISPs. How can I have the second connection take over when the primary one fails?

I have seen that it is possible to have two A records, each pointing to a different IP, but it has several problems. What's the real solution to this? I imagine this is a very common issue.

Thanks in advance!
