Correct way to write header has multi values in Java web

Question

I am handling HTTP header 'Content-Language' for multi languages. I have 2 ways:

WAY1:

 // setHeader
 response.setHeader("Content-Language", "en, fr"); // Using ',' as seperator

WAY2:

 // addHeader ----- Not setHeader

 response.addHeader("Content-Language", "en");
 response.addHeader("Content-Language", "fr");

My question is: Are these two ways equivalent? Which one should be used?

Thank you!

You can use both variants. In both cases a response header Content-Language: en, fr will be sent.

Calling response.addHeader multiple times for the same header name produces a concatenated version of the header values separated by a ", ".
