+You can also customize the warm-up behavior with one or more of the following [app settings](web-sites-configure.md):
 
 - `WEBSITE_SWAP_WARMUP_PING_PATH`: The path to ping to warmup your site. Add this app setting by specifying a custom path that begins with a slash as the value. For example, `/statuscheck`. The default value is `/`. 
 - `WEBSITE_SWAP_WARMUP_PING_STATUSES`: Valid HTTP response codes for the warm-up operation. Add this app setting with a comma-separated list of HTTP codes. For example: `200,202` . If the returned status code is not in the list, the warmup and swap operations are stopped. By default, all response codes are valid.
