-## When this setting is commented out, Invidious companion is not used.
-## Otherwise, Invidious will proxy the requests to Invidious companion.
-## 
-## Note: multiple URL can be configured. In this case, invidious will
-## randomly pick one every time video data needs to be retrieved. This
-## URL is then kept in the video metadata cache to allow video playback
-## to work. Once said cache has expired, requesting that video's data
-## again will cause a new companion URL to be picked.
-##
-## The parameter private_url needs to be configured for the internal
-## communication between the companion and Invidious.
-## And public_url is the public URL from which companion is listening
-## to the requests from the user(s).
-##
-## If you are using a reverse proxy then you will probably need to
-## configure the public_url to be the same as the domain used for Invidious.
-## Also apply when used from an external IP address (without a domain).
-## Examples: https://MYINVIDIOUSDOMAIN or http://192.168.1.100:8282
