+# Layer "Circuit Breaker"
+
+## Description
+
+Ce layer permet de bloquer l'accès à un site (ou une section de celui ci) ciblé par un proxy.
+
+## Type
+
+`circuitbreaker`
+
+## Options
+
+### `authorizedCIDRs`
+
+- **Type:** `[]string`
+- **Valeur par défaut:** `[]`
+- **Description:** Autoriser les adresses distantes contenues dans un des masques réseau (en notation ["CIDR"](https://en.wikipedia.org/wiki/Classless_Inter-Domain_Routing#CIDR_notation) définis à contourner la restriction d'accès.
+
+### `matchURLs`
+
+- **Type:** `[]string`
+- **Valeur par défaut:** `["*"]`
+- **Description:** Limiter l'action du layer à cette liste de patrons d'URLs. 
+
+    Par exemple, si vous souhaitez limiter votre restriction d'accès à l'ensemble d'une section "`/blog`" d'un site, vous pouvez déclarer la valeur `["*/blog*"]`. Les autres URLs du site ne seront pas affectées par la restriction.
+
+### `templateBlock`
+
+- **Type:** `string`
+- **Valeur par défaut:** `"default"`
+- **Description:** Bloc du template HTML pour effectuer le rendu de la page indiquant la restriction d'accès.
