I am using nginx as a reverse proxy for a tomcat setup, and everything works fine for the MOST part, the only issue I am having is that every request to an http address results in a new JSESSION ID being created(this doesn't happen in http), here is the relevant part of the NGINX configuration:

location / {

            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;

            proxy_set_header X-Forwarded-Proto https;
            proxy_redirect off;
            proxy_connect_timeout      240;
            proxy_send_timeout         240;
            proxy_read_timeout         240;
            proxy_pass http://localhost:8080;
      }

Any idea why I am constantly genning new jsessionids?
