servlets - Correct way to write header has multi values in Java web -


i handling http header 'content-language' multi languages. have 2 ways:

  1. way1:

    // setheader response.setheader("content-language", "en, fr"); // using ',' seperator

  2. way2:

    // addheader ----- not setheader  response.addheader("content-language", "en"); response.addheader("content-language", "fr");

my question is: these 2 ways equivalent? if no. 1 correct?

thank you!

you can use both variants. in both cases response header content-language: en, fr sent.

calling response.addheader multiple times same header name produces concatenated version of header values separated ", ".
