Surge can update a config file from a URL automatically. If the config starts with
#!MANAGED-CONFIG http://test.com/surge.conf interval=60 strict=true
The config can only be updated when Surge main application is running.
Note: The new config in remote should also contain #!MANAGED-CONFIG line. Otherwise the config will become a regular one.
interval: Optional, s (Default: 86400s).
Determine how long the config will be updated.
strict: true or false (Default: false).
If strict is true, Surge will require a force update after the interval arrives. Otherwise if the update fails the user may still use the outdated config.
Note: Even when strict is true, the user still can start Surge by widget or VPN switch in Settings.
