I'm not sure it matches what you currently have in mind, but what I
would do is set up www.myserver/app1 with mod_proxy to a standalone
Plack/Dancer process for the app. You would need something like this
in your VirtualHost for each app:
ProxyPass /app1 http://localhost:5000/app1
You'd also have to manage starting, stopping and reloading each of your
apps on its own, with a dedicated port, like 5000 in the line above.
If you wanted to combine your apps into one, you can do that with
Plack::Builder in a single app.psgi script. Then you get the benefit
of only having one script to start and stop, and one port. I currently
do that with one of my apps to separate the AJAX-specific stuff, based
on code I found in Dancer2::Cookbook:
use lib "$FindBin::Bin/../lib";
mount '/' => newtlc->to_app;
mount '/api' => newtlc::API->to_app;
