[Dancer-users] serving static and dynamic content separately

[Mr. Puneet Kishor]

I think I've got this solved. I had a fundamental misunderstanding of how virtual hosts worked, and now I think I am on top. Once I get everything sorted out, I would like to contribute a section to deploying Dancer apps so other miserable sods fighting with deployment issues can cut their misery in half.

My intent is to have apache2 serve some static content and some dynamic apps, both with domain names and those as sub-folders of the document root, and also serve some dynamic apps, both with domain names and without, proxied behind apache2.
