24:     end

29:       cache_control['no-cache'] ||
30:         env['HTTP_PRAGMA'] == 'no-cache'
31:     end
request_method ()

The HTTP request method. This is the standard implementation of this method but is respecified here due to libraries that attempt to modify the behavior to respect POST tunnel method specifiers. We always want the real request method.
