I cheated (well, some would say "made a reasonable decision not 
to reinvent the wheel"): I ran two copies of the application and 
both talked to the same database (which itself has a replication 
feature for failover, so any one server could go down at a time 
without breaking things, but two down at once would most likely 
have been a problem). Session storage was done as a special case 
of database setup.

The application itself didn't know and didn't need to know about 
the server setup. We never hit a point where this was 
problematic. If it took off to millions of users, perhaps things 
would need to change, but it worked fine with our actual scale 
(we made a modest profit for the years it stayed up, so I don't 
consider it a failure per se, but as I said, the company 
eventually pivoted).
