setHeader #

Sets a response header, with the same behavior as Node.js response.setHeader. Header names are case-insensitive.

If the header is already set:

• standard single-value headers (Content-Type, Content-Length, Authorization, ETag, Expires, Retry-After, User-Agent...) are overwritten;
• Set-Cookie values are added to an array;
• any other value is appended to the existing one, separated by , .

The value is converted to a string. Returns true.

Example #

request.response.setHeader('Cache-Control', 'no-cache');
request.response.setHeader('Cache-Control', 'no-store');

request.response.getHeader('cache-control');
// "no-cache, no-store"
