can you set up cookies in nginx?

i am working on AWS Elastic Beanstalk Instance, which runs Java application served through Nginx ( no load balancer in front, just a standalone instance ) I need to set cookie to catch client ip and client hostname. Is this possible to do it in nginx or should this be done in my Java code?

Below if my nginx configuration file:

location / { proxy_pass http://127.0.0.1:5000; proxy_http_version 1.1;

proxy_set_header Connection $connection_upgrade; proxy_set_header Upgrade $http_upgrade; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }
