 Changes Caddy's configuration at the named scope to the JSON body of the request. If the named scope is an array, POST appends; if an object, it creates or replaces.
 
-### Example
+As a special case, many items can be added to an array if:
+
+1. the path ends in `/...`
+2. the second-to-last element of the path refers to an array
+3. the payload is an array
+
+In this case, the elements in the payload's array will be expanded, and each one will be appended to the destination array.
+
+### Examples
 
 ```bash
 $ curl -X POST \
 	-H "Content-Type: application/json" \
-	-d '":2080"' \
+	-d '":8080"' \
 	"http://localhost:2019/config/apps/http/servers/myserver/listen"
 ```
 
+```bash
+$ curl -X POST \
+	-H "Content-Type: application/json" \
+	-d '[":8080", ":5133"]' \
+	"http://localhost:2019/config/apps/http/servers/myserver/listen/..."
