Research direction

Start with the app.psgi mount setup and the configuration or database initialization used by both mounted apps. Reproduce requests to foo.com and bar.com while checking which database each app selects; done means each app consistently uses only its own database. The issue names no source file or test beyond app.psgi.

Description

Question

I have two apps build using dancer2 hosted on two different domains say foo.com and bar.com
I am loading them via a app.psgi file

builder {
    mount 'https://foo.com/'      => foo->to_app;
    mount 'https://bar.com/' => bar->to_app;
    };

Both these apps access databases foodb and bardb each

I am frequently seeing "Error 500" messages while these databases are accessed. On checking the log it is usually because foo is trying to access its tables from bardb or bar is trying to access its tables in foodb.

It looks like the configuration of one app is leaking into another. I am not sure how to debug this. Any hints?
