# Caddy vars directive

[Caddy][] provides the [http.handlers.vars][] module, but it isn't available for use in a `Caddyfile`. Sometimes setting a variable might be useful but not worth abandoning the simplicity of the Caddyfile configuration format.

## Setup

Build with [xcaddy][]:

```

xcaddy build --with github.com/edudobay/caddy-varsdirective

```

## Motivation and example usage

Rewriting the URL in a PHP/FastCGI app is not so obvious (see [this thread](https://caddy.community/t/symfony-with-uri-prefix/10148/3) for an explanation). In this example, we remove the `/_api` prefix, if present, and also remove trailing slashes.

```

route {

	uri strip_prefix /_api

	uri strip_suffix /

	set_var resolved_uri {path}

	php_fastcgi localhost:9000 {

		env REQUEST_URI {http.vars.resolved_uri}

	}

}

```
