Multi server setup with WebApp behind reverse proxy

[mculibk]

Hi there!

I’m currently playing with a POC setup with a multi server Kopano config with “standalone” WebApp server located in a DMZ and behind a reverse proxy.

I went through the documentation and kinda “get it” but I’m wondering who is actually connecting to different backend kopano-servers?
Does the actual client (user web browser) tries to contact each server directly (via received redirects) or is (just) the WebApp server the one who speaks to different backend servers as needed?

As mentioned, my setup should look something like this:

user web browser --> Internet --> nginx reverse proxy --> webapp (dmz) --> kopano-server1 / kopano-server2 (lan)

Does the user web browser (still) needs to be aware of the multiple servers behind or will that be handled by the WebApp server alone?

Thanks for any info.
