difference "PUBLIC_INSTANCE_URL" & "PUBLIC_INTERNAL_INSTANCE"

Hi,

I would like to know what the difference is between the following two variables:

• PUBLIC_INSTANCE_URL
• PUBLIC_INTERNAL_INSTANCE

The most common settings you'll use are `PUBLIC_INSTANCE_URL`. Some selfhosters with `PUBLIC_SSR_ENABLED` set to true might want the instance url to be different for the server. You can use the `PUBLIC_INTERNAL_INSTANCE` variable for that.

The PUBLIC_INTERNAL_INSTANCE variable defines where the Photon instance is hosted, and is used when the Lemmy instance is at a different address. It's used for links in Photon, so for example when clicking a post you will be sent to the URL photon.lemmy.world instead of lemmy.world. It is not required when the Photon instance is hosted on the same URL as the Lemmy instance.

And in which scenario would the url for PUBLIC_INSTANCE_URL PUBLIC_INTERNAL_INSTANCE be different?

And in which scenario would the url for PUBLIC_INSTANCE_URL PUBLIC_INTERNAL_INSTANCE be different?
For example the photon instance on lemmy.world

The lemmy instance is at lemmy.world and the photon instance is at photon.lemmy.world

I did that too, but only with PUBLIC_INSTANCE_URL = https://photon.rollenspiel.forum

When SSR is enabled, that is the URL requests are made to by the server. Without it, it will default to PUBLIC_INSTANCE_URL
