Well I have a page accessed through a template. Let's call the template
x.tt. Now I want to somehow change the content of a div on that page. I
know how to do that. But the code is perl. If I redirect through another
route, it will reload the page or potentially have other issues as it
only returns a brief string (i.e) not JSON, or am I incorrect?

Hmmm, the Dancer part is "where to executables go that can be called via
a browser viewing a Dancer-generated template?
