Yeah, my application is working! What? It’s not working? What the heck? Rolling out server sent events (SSE) to production can be a hard way. In most situation it’s working fine, but sometimes the event sinks are not notified – or better – only notiefied after some minutes. Let’s solve the riddle.
Whats going on?
Due to older or misconfigured proxies, network elements, the data of a server sent event is tried to chunk. But that’s not the idea of SSE.
The post of Mike Talbot (see https://dev.to/miketalbot/server-sent-events-are-still-not-production-ready-after-a-decade-a-lesson-for-me-a-warning-for-you-2gie) helped me a lot to go in the right direction. And Kevin Douglas comment pointed out the solution ( https://dev.to/dunglas/comment/103cg )
Thanks a lot!
