Method directive

caddyconfig/caddyfile/parse.go:636–681

directive collects tokens until the directive's scope closes (either end of line or end of curly brace block). It expects the currently-loaded token to be a directive (or } that ends a server block). The collected tokens are loaded into the current server block for later use by directive setup funct
