Caddyfile Directives Directives are functional keywords that appear within site blocks. Sometimes, they may open blocks of their own which can contain subdirectives, but directives cannot be used within other directives unless noted. For example, you can't use basic_auth inside a file_server block, because file_server does not know how to do authentication. However, you may use some directives within special directive blocks like handle and route because they are specifically designed to group HTTP handler directives. Syntax Directive Order Sorting Algorithm The following directives come standard with Caddy, and can be used in the HTTP Caddyfile: Directive Description abort Aborts the HTTP request acme_server An embedded ACME server basic_auth Enforces HTTP Basic Authentication bind Customize the server's socket address encode Encodes (usually compresses) responses error Trigger an error file_server Serve files from disk forward_auth Delegate authentication to an external service fs Set the file system to use for file I/O 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 intercept
