##
#pool_size: 100
##
## Enable/Disable the use of QUIC (HTTP/3) when connecting
## to the youtube API and websites ('youtube.com', 'ytimg.com').
## QUIC's main advantages are its lower latency and lower bandwidth
## use, compared to its predecessors. However, the current version
## of QUIC used in invidious is still based on the IETF draft 31,
## meaning that the underlying library may still not be fully
## optimized. You can read more about QUIC at the link below:
## https://datatracker.ietf.org/doc/html/draft-ietf-quic-transport-31
##
## Note: you should try both options and see what is the best for your
## instance. In general QUIC is recommended for public instances. Your
## mileage may vary.
##
## Note 2: Using QUIC prevents some captcha challenges from appearing.
## See: https://github.com/iv-org/invidious/issues/957#issuecomment-576424042
##
## Accepted values: true, false
## Default: false
##
#use_quic: false
##
## Additional cookies to be sent when requesting the youtube API.
