A Steering delivery service will have target delivery services configured for it with weights assigned to them. Traffic Router uses the weights to make a consistent hash ring which it then uses to make sure that requests are routed to a target based on the configured weights. This consistent hash ring is separate from the consistent hash ring used in cache selection.</p> <p>Special regular expressions called Filters can also be configured for target delivery services to pin traffic to a specific delivery service.
