[pm-h] Looking for PSGI web server Daemon

[John Lightsey]

Is there some advantage in using a Perl PSGI daemon rather than a more
standard combination of Apache+ModPerl+PSGI or Nginx+FastCGI+PSGI?

The utility of a standalone PSGI server seems pretty obvious for
development, but not so obvious for production deployments. I would
think that the performance hit for static files would be significant
enough to outweigh the benefits of using a dedicated PSGI server.

Here's a cool URL mapper for Plack apps.  It works great for Plack apps but it fails to pull in more than the first Mojo app.  I have no idea why but load_psgi (`do "$filename"`) must work differently after the first Mojo app is loaded. Error: "Can't use string ("Mojolicious::Commands") as a subroutine ref while "strict refs" in use at /usr/share/perl5/vendor_perl/Plack/Middleware/Auth/Basic.pm line 30."
