FUNCTIONS

       match_if
             enable match_if addr('127.0.0.1'), "Plack::Middleware::ReverseProxy";
             enable match_if sub { $_[0]->{REMOTE_ADDR} eq '127.0.0.1' }, "Plack::Middleware::ReverseProxy";

           As like Plack::Builder's enable_if enable middleware if given conditions return true

       addr
             addr('127.0.0.1');
             addr([qw!192.168.0.0/24 127.0.0.1 ::1!]);
             addr('!','127.0.0.1');

           return true if REMOTE_ADDR is found in the CIDR range. If first argument is '!',
           return the opposite result.  This function supports IPv6 addresses

       path
             path('/')
             path(qr!^/(\w+)/!)
             path('!', qr!^/private!)

           matching PATH_INFO

       method
             method('GET')
             method(qr/^(get|head)$/i)
             method(qw(GET HEAD))
             method('!','GET')
             method('!', qr/^(post|put)$/i)
             method('!', qw(POST PUT))

       header
             header('User-Agent',qr/iphone/)
             header('If-Modified-Since') #exists check
             header('!', 'User-Agent',qr/MSIE/)

       browser
             browser(qr/\bMSIE (7|8)/)
             browser('!',qr!^Mozilla/4!);

           Shortcut for header('User-Agent')

       all
             all( method('GET'), path(qr!^/static!) )

           return true if all conditions are return true

       any
             any( path(qr!^/static!), path('/favicon.ico') )

           return true if any condition return true

EXPORT

         use Plack::Builder::Conditionals -prefx => 'c';
         # exports "c_match_if, c_addr, c_path, c_method, c_header, c_any, c_all"
