Have you looked into the Net::HTTP class?  Some simple code to see if
something exists or not could run something like:

require 'net/http'
h = Net::HTTP.new('munge.net')
begin
    resp, data = h.get('/doesntexist?foo=bar')
rescue Net::ProtoFatalError => splat
    print "Are you sure about that? -- " + splat
end
