// RegisterTargetsRequest returns a request value for making API operation for
// Elastic Load Balancing.
//
// Registers the specified targets with the specified target group.
//
// If the target is an EC2 instance, it must be in the running state when you
// register it.
//
// By default, the load balancer routes requests to registered targets using
// the protocol and port for the target group. Alternatively, you can override
// the port for a target when you register it. You can register each EC2 instance
// or IP address with the same target group multiple times using different ports.
//
// With a Network Load Balancer, you cannot register instances by instance ID
// if they have the following instance types: C1, CC1, CC2, CG1, CG2, CR1, CS1,
// G1, G2, HI1, HS1, M1, M2, M3, and T1. You can register instances of these
// types by IP address.
//
// To remove a target from a target group, use DeregisterTargets.
//
//    // Example sending a request using RegisterTargetsRequest.
//    req := client.RegisterTargetsRequest(params)
//    resp, err := req.Send(context.TODO())
//    if err == nil {
