+# Layer "Rewriter"
+
+## Description
+
+Ce layer permet de modifier dynamiquement certains attributs de requêtes/réponses transitant par le proxy.
+
+## Type
+
+`rewriter`
+
+## Schéma des options
+
+Les options disponibles pour le layer sont décrites via un [schéma JSON](https://json-schema.org/specification). Elles sont documentées dans le [schéma visible ici](../../../../internal/proxy/director/layer/rewriter/layer-options.json).
+
+## Moteur de règles
+
+Les options `rules.request` et `rules.response` permettent de définir des listes de règles utilisant un DSL modifiant de manière dynamique les attributs des requêtes/réponses transitant par le proxy.
+
+Les listes d'instructions sont exécutées séquentiellement.
+
+Bouncer utilise le projet [`expr`](https://expr-lang.org/) comme DSL. En plus des fonctionnalités natives du langage, Bouncer ajoute un certain nombre de fonctions spécifiques au contexte d'utilisation.

+## Proxy
+
+Un proxy est une entité logique définie par les propriétés suivantes:
+
+- Il possède **un ou plusieurs filtres d'origine** sous la forme de motifs d'URL avec le caractère `*` comme joker. Ces filtres identifient le ou les URLs associées au proxy.
+- Il peut avoir **zéro ou une URL cible**, qui servira de base pour la réécriture des requêtes. Si l'URL est absente, on parle alors de "passthrough" (voir note).
+- Il peut avoir **zéro ou plusieurs "layers" associés**.
+- Il peut être **activé ou désactivé**.
+- Il a **un poids qui définit son niveau de priorité** dans la pile de traitement (plus son poids est élevé plus il est prioritaire).
+
+Pour résumer un proxy répond à la question "_Quelle URL orienter vers quel serveur cible ?_".
+
+> **Passthrough**
+>
+> Un proxy "passthrough" est un proxy n'ayant pas d'URL cible (champ vide). Dans ce cas si les motifs d'URLs correspondent à l'URL de la requête Bouncer appliquera les layers associés puis passera la main aux proxies suivants.

+# Le cas du "virtual hosting"
+
+De nombreux serveurs HTTP utilisent le mécanisme du ["virtual hosting"](https://en.wikipedia.org/wiki/Virtual_hosting) afin d'héberger plusieurs sites/applications différentes sur un même serveur, se basant alors sur l'entête HTTP `Host` pour effectuer le routage.
+
+## Exemple
+
+Pour exemple, avec le site [example.net](https://example.net) il est facile de tester ce type de comportement. Ainsi, en exécutant une requête HTTP avec `curl`:
+
+```shell
+curl -I https://example.net
+```
+
+On obtient le résultat suivant:
+
+```
+HTTP/2 200
+accept-ranges: bytes
+age: 568237
+cache-control: max-age=604800
+content-type: text/html; charset=UTF-8
+date: Thu, 27 Jun 2024 08:32:46 GMT
+etag: "3147526947"
+expires: Thu, 04 Jul 2024 08:32:46 GMT
+last-modified: Thu, 17 Oct 2019 07:18:26 GMT
+server: ECAcc (bsb/2789)
+x-cache: HIT
+content-length: 1256
+```
+
+Ce résultat indique que le serveur a correctement orienté notre requête (code HTTP `200`) et qu'il nous a renvoyé la réponse attendue.
+
+Si maintenant on modifie l'entête `Host` de notre requête pour la remplacer par une valeur arbitraire:
+
+```shell
+curl -I -H 'Host: localhost:8080' https://example.net
+```
+
+On obtient alors le résultat:
+
+```
+HTTP/2 404
+content-type: text/html
+date: Thu, 27 Jun 2024 08:38:04 GMT
+server: ECAcc (bsb/2789)
+content-length: 345
+```
+
+Le serveur nous répond avec un code HTTP `404`, indiquant qu'il n'a pas trouvé la page demandée.
+
+> **Note**
+> Le code HTTP retourné par le serveur peut varier en fonction des implémentations. Parfois la requête sera orientée vers la page par défaut, parfois vous recevrez un code d'erreur HTTP comme `404`, `421`, etc.
+
+## Avec Bouncer
+
+Ce mécanisme peut parfois poser problème avec Bouncer car par défaut celui ci n'effectue pas de réécriture de l'entête `Host`. Pour exemple:
+
+1.  Créez puis activez un nouveau proxy pointant vers https://example.net
+
+    ```shell
+    bouncer admin proxy create --proxy-name example --proxy-to https://example.net
+    bouncer admin proxy update --proxy-name example --proxy-enabled=true
+    ```
+
+2.  Avec `curl`, faites une requête sur votre nouveau proxy:
+
+    ```shell
+     curl -I http://localhost:8080
+    ```
+
+    La réponse devrait ressembler à:
+
+    ```
+    HTTP/1.1 404 Not Found
+    Content-Length: 345
+    Content-Type: text/html
+    Date: Thu, 27 Jun 2024 08:49:05 GMT
+    Server: ECAcc (bsb/2789)
+    ```
+
+    On retrouve bien notre code HTTP `404` tel que vu plus haut. En effet, vu que l'on accède au proxy Bouncer avec `http://localhost:8080` alors le serveur distant recevra l'entête `Host: localhost:8080`.
+
+### Comment corriger la situation ?
+
+Le layer [`rewriter`](../references/layers/rewriter.md) a été implémenté notamment pour répondre à ce type de cas. Voyons comment l'utiliser:
+
+1. Créez puis activez un nouveau layer pour votre proxy `example`:
+
+   ```bash
+    # Création du layer
+    bouncer admin layer create --proxy-name example --layer-name host-rewrite --layer-type rewriter
+
+    # Mise à jour et activation du layer
+    bouncer admin layer update \
+        --proxy-name example \
+        --layer-name host-rewrite \
+        --layer-options '{ "rules": { "request": ["set_host(\"example.net\")"] } }' \
+        --layer-enabled=true
+   ```

+1. Se positionner dans le répertoire puis lancer l'environnement avec la commande `docker compose`:
 
-    ```bash
+   ```bash
-    cd misc/docker-compose
+   cd misc/docker-compose
-    docker-compose up
+   docker compose up
-    ```
+   ```
 
 2. Entrer dans le conteneur `bouncer-admin` puis créer un jeton d'accès:
 
-    ```bash
+   ```bash
-    docker-compose exec bouncer-admin /bin/sh
+   docker compose exec bouncer-admin /bin/sh
-    bouncer auth create-token --role writer > .bouncer-token
+   bouncer auth create-token --role writer > .bouncer-token
-    ```
+   ```
 
 3. Créer un proxy via le CLI:
 
-    ```bash
+   ```bash
-    bouncer admin proxy create --proxy-name myproxy --proxy-to "https://www.cadoles.com/"
+   bouncer admin proxy create --proxy-name myproxy --proxy-to "https://www.cadoles.com/"
-    bouncer admin proxy update --proxy-name myproxy --proxy-enabled=true
+   bouncer admin proxy update --proxy-name myproxy --proxy-enabled=true
-    ```
+   ```
 
 4. Via votre navigateur, accéder à l'URL http://127.0.0.1:8080. La page du site Cadoles devrait s'afficher. Dans le log de la commande `docker-compose up` vous devriez voir que les requêtes sont routées à tour de rôle sur les 3 instances de Bouncer en exécution.
+
+5. Stopper l'environnement:
+
+   ```
+   docker compose down -v
+   ```
