Description

Nginx combines multiple link headers in a wrong way when being used as a HTTP reverse proxy.

Multiple link headers are concatenated to a single link header, separated with a ";". However, multiple link header values must be concatenated with ",".

Please clarify. No header concatenation is done by nginx, except for Cookie, X-Forwarded-For, and Cache-Control headers when accessing them via $http_* variables.
