Is reverse proxy server like Varnish affects how wpforo cache works?
Please read this support topic:
https://wpforo.com/community/how-to-and-troubleshooting-2/wpforo-with-varnish/#post-28711
It's better to exclude wpForo forum page from the Varnish, here is a good article:
https://support.cloudways.com/how-to-exclude-url-from-varnish/
wpForo has its own cache system, so you should exclude it from all cache solutions. Here is the FAQ topic: https://wpforo.com/community/faq/wpforo-and-cache-plugins/
I am not using Cloudways. I am using Godaddy + Cloudflare + W3 total cache plugin.
Here are what i have done:
1. except /community/* page from W3 total cache plugin (Database + Page + Browser and all),
2. Bypass cache /community/* page from cloudflare cache
The only thing i do not know is, how can i exlude /community/* in Varnish.
You recommendation is correct if the user is using cloudways only.
Any advise? Thanks!
I'm sorry but I have no idea. The best way is connecting to hosting service support and ask them do that.
