RCR - Caching Mechanism

• RCR is reading the last saved config from the cache file on the disk, and if successful, that config gets applied
• If the app is connecting for the first time and there is no cache file, RCR will apply the default values for each variable type (0 for int, "" for string, etc...)
• RCR makes a request, and if successful, it overrides the previously applied cached config
• The last received config also overrides the values in the cache file
• This mechanism is applied for all platforms except for consoles, as writing on the disc for consoles requires special platform permissions

1. if the user was never connected before and has no connection, default values should be applied.
2. if the user was never connected before and now has a connection, remote values should be applied and written in the cache on the local disk
3. If the user was connected at least once, and now has no connection, cached values should be applied
4. If the user was connected at least once, and now has a connection, remote values should be applied as they overwrite cached values
