Missing configuration keys in documentation

Hi

I am reading the configuration file documentation (https://www.traccar.org/configuration-file/) in order to know what configuration options are available for traccar.

However, I realised that some configuration keys in the default configuration file (https://github.com/traccar/traccar/blob/master/setup/default.xml) are not described in the documentation page, for example, the media.path key.

Also, I realised that some configuration keys in the source code (https://github.com/traccar/traccar/blob/master/src/main/java/org/traccar/config/Keys.java) are not described in the documentation page or included in the default configuration file, for example, the forward.header key.

The question here is: Can I set all keys included in the Keys.java file by set them in my traccar.xml config file? What I mean is, I don't know if this is just a lack of documentation issue, or if it's only possible to customize the options documented on the documentation page.

I would greatly appreciate your help and I hope I have been clear with my doubt.

Exactly, I share same question.
Is there a reason behind this code/documentation mis-alignment, or is just a matter of versioning?

It's just the matter of time till we migrate everything to Keys.java.

thanks!
