-### `Edge.disconnect(): void`

-}
-
-function echo(ctx, params) {

-}

+<script src="/edge/sdk/client.js"></script>
 ```
 
-**Côté client**
+Vous pourrez ensuite accéder aux variables globales suivantes:
 
-```js
-Edge.connect().then(() => {
-    Edge.rpc("echo", { hello: "world!" })
-        .then(result => console.log(result))
-        .catch(err => console.error(err));
-});

-### `Edge.upload(blob: Blob, metadata: Object): Promise`

-### `Edge.blobUrl(bucketName: string, blobId: string): string`
-
-> `TODO`

+# Module `fetch`
+
+Ce module permet l'accès à des ressources distantes (sur Internet) depuis votre application.
+
+## Fonctions de rappel
+
+Pour permettre aux utilisateurs d'accéder à des ressources distantes, vous devez déclarer la fonction `onClientFetch(ctx: Context, url: string, remoteAddr: string)` dans le fichier `server/main.js` de votre application.
+
+### `onClientFetch(ctx: Context, url: string, remoteAddr: string)`
+
+#### Usage
+
+**Côté client**
+```js
+// Création d'une URL "locale" permettant d'accéder à la ressource distante
+var url = Edge.externalUrl("http://example.com")
+
+// Vous pouvez utiliser l'URL comme attribut `src` d'une balise <img> par exemple
+// ou effectuer une requête fetch() avec celle ci.
+fetch(url).then(res => res.text()).then(content => console.log(content));
+```
+
+**Côté serveur**
+```js
+function onClientFetch(ctx, url, remoteAddr) {
+    // Autoriser la récupération de l'URL demandée ou non
+    // Dans cet exemple, seule l'URL externe 'http://example.com' est autorisée
+    // Les autres URLs recevront une erreur HTTP 403 - Forbidden
+    var authorized = url === "http://example.com"
+
+    return { allow: authorized };
+}
+```
