Yes thanks.
I did find a simpler way though. The '' were the problem.

domain = ENV['HTTP_HOST']
if domain =~ /domain1.com/;printf "<h2>Welcome to Domain 1</h2>"
elsif domain =~ /domain2.com/;printf "<h2>Welcome to Domain 2</h2>"
elsif domain =~ /domain3.com/;printf "<h2>Welcome to Domain 3</h2>"
elsif domain =~ /domain4.com/;printf "<h2>Welcome to Domain 4</h2>"
elsif domain =~ /domain5.com/;printf "<h2>Welcome to Domain 5</h2>"
end
