You're right, it doesn't match /media/foo/bar. The reason is simple: the
syntax for routes, as defined by Sinatra, is not pure regex, and avoids
matching a slash on purpose.[1]

The idea is that you could declare a variable being there, without providing
a name, and then splat() returns it.

Since the route syntax doesn't cover regexp.

If you know the level, and you want to be explicit, you can try the default
route syntax: '/media/*/*'.
However, you will most likely prefer a regular expression (which you tried
earlier), and Dancer allows that very easily since Perl considers regexes as
first class:
get qr/.../ => sub { ... };

We prefer to wrap qr() with something other than slashes, so we don't get
into a backslash fight:
get qr{ / media / (.*) }x => sub { ... };

Enjoy!
