I would have used sessions if these shared variables typically

state of the server (its filesystem for example) and I believe that they
are best implemented insulated from sessions which are more suited to
client-side stuff.

I do not look to Dancer code for some time, but I almost sure that vars are not preserved across requests.

So, the solution would be to declare your own global hash table for keep that information.

Indeed, I believe $var is a such a hash table. I have a single App.pm and in that circumstance, $var is available to all route handlers.

Is my understanding incorrect?

But if there was an error in my logic, I would certainly consider using
sessions

Thanks

Don't you want to use sessions to do these sort of things ?
