If you use rsync then you end up with a duplicate of the cache on one
machine on the other one. Any files deleted from the machine will be
deleted from the other.
The only thing that you should do is delete the contents of the
monitor directory on the machine that you are copying to or you may
find that all the monitored pages don't get requested if the timestamp
changes.

The source code!
The file format should be easy to work out. Just look at the files,
those starting with a 'U' are the name of the URL for the files
starting with a 'D'. Those starting with a 'O' are requests to be
made and not pages that are cached.

I use the latter option. Only one of the two machines is ever on the
internet, when I am away from one machine with the other it remains
disconnected.

You shouldn't have any that are zero bytes long, that is strange.

The contents are what the server sends back.

There isn't one unless you count the files whose names start with
'U'. There is no file for the cache status of each site since
everything is done on a URL-by-URL basis.
