 Route ordering is very important when a request can meet the route rules of multiple routes. You should order the routes with more complex route rules first. If you do not define a route order, routes are ordered in the order they were created.

If the route order was reversed and route one had no route rules, Flex Gateway would direct all requests to route one before any `GET` requests could reach route two.
