I am looking for a way to rename a cookie in a Set-Cookie header on a per-server basis. Each server that I'm proxying generates a "Set-Cookie: sessionid=xxxxxx" header. I would like to create some sort of rule that would rename that cookie "sessionid_xyz=xxxxxx" when sending to the client, then rename it back to session_id when sending back to the proxy_pass location Is tby jlange - Nginx Mailing List - English
