Question Server Sent Events (SSE) problem

[Manfred Beck]

Server operating system version

AlmaLinux 8.10 (Cerulean Leopard)

Plesk version and microupdate number

Plesk Obsidian 18.0.79 Update #4

In my development environment everything works fine

JQuery:
source = new EventSource(processor);
source.onmessage=function(event) {...
PHP:
header('Content-Type: text/event-stream');
header('Cache-Control: no-cache');
...processing query result, echoing each record details to frontend, close connection, done.

In Plesk all results come at once, so I presume it is a cache problem. If so, how can I change the cache settings for just one domain? Any help highly appreciated.

Found a solution, worder if this is recomemnded:

• proxy_buffering off;

• proxy_cache off;

• chunked_transfer_encoding on;

• proxy_read_timeout 24h;

• proxy_send_timeout 24h;

ok, finally found a solution, forget all NGINX additional directives.

header( 'X-Accel-Buffering: no' ); // This is useful to disable buffering in nginx through headers.

does the job!!!
