Handlers connect web servers with Rack.
Rack includes Handlers for Mongrel, WEBrick, FastCGI, CGI, SCGI and LiteSpeed.
Handlers usually are activated by calling MyHandler.run(myapp). A second optional hash can be passed to include server-specific configuration.

Transforms server-name constants to their canonical form as filenames, then tries to require them but silences the LoadError if not found
Naming convention:
Foo # => 'foo' FooBar # => 'foo_bar.rb' FooBAR # => 'foobar.rb' FOObar # => 'foobar.rb' FOOBAR # => 'foobar.rb' FooBarBaz # => 'foo_bar_baz.rb'
