I’m using some Mattermost instances proxied by an Nginx service. The Nginx service is configured as you suggested in your doc but with one difference. I have several Mattermost behind one Nginx virtualhost. Can due to this reason and difference with your proposed config, have impredictible results in different Mattermost instances due to cached content?. Each instance is accesed with a completely different URL. For instance :
The question is can something not corresponding to a Mattermost instance, appear there due to a non corresponding to the instance cached content?. Would be better to be using different vhosts?. The main reason I use this config is for simplicity and due to the wilcard certificate I have bought… for avoid having issues with that too…
Have you mates ever experienced issues like this (supposed and not reproduced yet at least) with the cache?.
