You have an application hosted on an ASG with a minimum capacity value of two and a maximum capacity value of four. You've also configured target tracking scaling to maintain an average CPU utilization of 60%. You notice a lot of traffic on your application, and it easily scales to four instances. 

What happens if the requests keep increasing and the average CPU utilization reaches 90%?

The IP address is preserved and can be found in the request that reaches the instance from the ALB.

The request header will have an entry ```X-Forwarded-For```, which will contain the client's IP address.

The request header will have an entry ```X-Forwarded-Proto```, which will contain the client's IP address.

The request header will have an entry ```X-Forwarded-Port```, which will contain the client's IP address.

Your application is hosted on an ASG that uses an ALB frontend. The application requires the client's IP address from the request to process their requests. 

How can your application see the client's IP address?
