title: Nginx: allow only certain cookies in http response
body: <p>I'm using playframework and nginx. playframework may add following cookies to http response: PLAY_SESSION, PLAY_FLASH, PLAY_LANG. <br>
  I want to make sure that only above cookies (PLAY_*) are allowed in nginx level. If there are other cookies (let's say they're added accidentally) they should be removed by nginx. <br>
  How can I allow only predefined cookies in http response in nginx?</p>
  
  <p>PS: If it's not possible to solve this issue in nginx, I need to fix by using playframework.</p>
