/** * @Robots(directive="noarchive") * @Robots(directive="unavailable_after" value="25 Jun 2010 15:00:00 PST") */ public function showAction() { }, <sub>(*10)</sub>

### Configuration

Set `block_all` to true to always set the `X-Robots-Tag` header to `none`. This will block all indexing and serving. Default: false

This is helpful to set an **environment specific robots header** so as to prevent search engines from indexing dev and test environments. Simple place the following configuration in your config_dev.yml and/or config_test.yml.

``` yaml
four_labs_robots:
    block_all: true
