# Disabling update check

On intranet/internal WordPress installations it might be required to block external requests, including the plugin feature to check for updates.

To do that, use either the [WP\_HTTP\_BLOCK\_EXTERNAL](https://codex.wordpress.org/Editing_wp-config.php#Block_External_URL_Requests) constant in your **wp-config.php** file, that blocks all external requests globally on the whole WordPress installation:

```
define( 'WP_HTTP_BLOCK_EXTERNAL', true );
```

..or, if you wish blocking requests **only** from Ajax Search Pro, then use the *ASP\_BLOCK\_EXTERNAL* constant:

```
define( 'ASP_BLOCK_EXTERNAL', true );
```
