以下是 Caddyfile 的標准指令。
| acme_server | An embedded ACME server |
| basicauth | Enforces HTTP Basic Authentication |
| bind | Customize the server's socket address |
| encode | Encodes (usually compresses) responses |
| file_server | Serve files from disk |
| handle | A mutually-exclusive group of directives |
| handle_errors | Defines routes for handling errors |
| handle_path | Like handle, but strips path prefix |
| header | Sets or removes response headers |
| import | Include snippets or files |
| log | Enables access/request logging |
| php_fastcgi | Serve PHP sites over FastCGI |
| redir | Issues an HTTP redirect to the client |
| request_header | Manipulates request headers |
| respond | Writes a hard-coded response to the client |
| reverse_proxy | A powerful and extensible reverse proxy |
| rewrite | Rewrites the request internally |
| root | Set the path to the site root |
| route | A group of directives treated literally as single unit |
| templates | Execute templates on the response |
| tls | Customize TLS settings |
| try_files | Rewrite that depends on file existence |
| uri | Manipulate the URI |
指令的語法格式如下：
directive [<matcher>] <args...> { subdirective [<args...>] }
< > 中使用實際的值替換，[ ] 代表是可選的參數，... 代表一個或多個值。
大多數指令接受 [<matcher>] 來過濾請求，表示不同的請求使用不同的指令。
許多指令操縱 HTTP 處理程序鏈。這些指令的求值順序很重要，因此默認的順序被硬編碼到 Caddy 中。
root
header
redir
rewrite
uri
try_files
basicauth
request_header
encode
templates
handle
handle_path
route
respond
reverse_proxy
php_fastcgi
file_server
acme_server
如果需要自定義順序，可以使用 order 全局選項，或者 route 指令。
