Portainer not showing real time logs - they seem to be stuck (even if I refresh & restart)

Problem Description

Portainer doesn't seem to be getting the latest logs for an Nginx container.

Actually - I've just realized what it was.
I had already prepared a very detailed bug report, but I see the problem is that I enabled a default "expires" entry in Nginx, and that's why the logs aren't updating.
It's because the "logs" GET request that Portainer calls is returning the last cached request.

I see the mimetype is application/vnd.docker.raw-stream, which I'm going to add to the exceptions.

But here's a suggestion -- you could add an extra parameter to the query string, with a timestamp + random number, e.g. &r=13458151548753, to ensure this never happens, even if there is a misconfiguration in the server.

Thanks!

Hi @ghnp5 Thanks for this, I have raised this internally for conversation. Since this is not a bug and more a feature request I have adjusted the tags

Thanks! No problem.

Another suggestion could be to simply add an "expires" header to the responses, to "now" date, or a date in the past.
Maybe that's better than my initial suggestion above.
