How to set header content-type text/event-stream?

Hi, all.
I want to create data text/event-stream for Server Sent Event. I wrote code like this.

PHP Code:

header('Content-Type: text/event-stream');
header('Cache-Control: no-cache');
echo "Data:test\n\n"; 


but, the results I get are like this.
HTTP/1.1 200 OK
Server: nginx/1.14.0 (Ubuntu)
Content-Type: text/html; charset=UTF-8
Transfer-Encoding: chunked
Connection: keep-alive
Cache-Control: no-cache
Cache-control: no-store, max-age=0, no-cache

data: Hallo:  

Can anyone help me, please?

You should always use the Response object that is in every controller to set the headers instead of setting them directly now. Something like:

Code:

$this->response->setHeader('Content-Type', 'text/event-stream');

By default - caching is turned off through the headers so you don't have to specify that. Unless changed it sets Cache-Control to no-store, max-age=0, no-cache.
