## Terminologie
Voici une liste des termes utilisés dans le lexique Bouncer.
### Proxy
Un "proxy" est une entité logique définissant le relation suivante:
- Un ou plusieurs patrons de filtrage sous la forme d'un patron d'URL avec le caractère `*` comme caractère générique. Ceux ci identifient le ou les domaines/chemins associés à l'entité;
- Une URL cible qui servira de base pour la réécriture des requêtes.
Un "proxy" peut avoir zéro ou plusieurs "layers" associés.
Un "proxy" peut être activé ou désactivé.
Un "proxy" a un poids qui définit son niveau de priorité dans la pile de traitement (plus son poids est élevé plus il est prioritaire).
### Layer
Un "layer" (calque) est une entité logique définissant un traitement à appliquer aux requêtes et/ou aux réponses transitant par un proxy.
Un "layer" peut être activé ou désactivé.
Un "layer" a un poids qui définit son niveau de priorité dans la pile de traitement (plus son poids est élevé plus il est prioritaire).

# 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.
### Fonctions
#### Communes
##### `add_header(name string, value string)`
Ajouter une valeur à un entête HTTP via son nom `name` et sa valeur `value`.
##### `set_header(name string, value string)`
Définir la valeur d'un entête HTTP via son nom `name` et sa valeur `value`. La valeur précédente est écrasée.
##### `del_headers(pattern string)`
Supprimer un ou plusieurs entêtes HTTP dont le nom correspond au patron `pattern`.
Le patron est défini par une chaîne comprenant un ou plusieurs caractères `*`, signifiant un ou plusieurs caractères arbitraires.
#### Requête
##### `set_host(host string)`
Modifier la valeur de l'entête `Host` de la requête.
##### `set_url(url string)`
Modifier l'URL du serveur cible.
#### Réponse
_Pas de fonctions spécifiques._
### Environnement
Les règles ont accès aux variables suivantes pendant leur exécution. **Ces données sont en lecture seule.**
#### Requête
##### `request`
La requête en cours de traitement.
```js
{
method: "string", // Méthode HTTP
host: "string", // Nom d'hôte (`Host`) associé à la requête

},
remoteAddr: "string", // Adresse du client HTTP à l'origine de la requête
requestUri: "string" // URL "brute" associée à la requêtes (avant opérations d'assainissement, utiliser "url" plutôt)

# Terminologie
Voici une liste des termes utilisés dans le lexique Bouncer.
## 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.
## Layer
Un layer est une entité logique définie par les propriétés suivantes:
- Il a **un type auquel est associé un schéma d'options** permettant de configurer son comportement.
- 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 layer répond à la question "_Quel traitement appliquer à la requête et/ou réponse ?_".

# 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
```
> **Les règles**
>
> Le layer `rewriter` permet la modification des requêtes/réponses via un moteur de règles.
>
> [Voir la page du layer pour plus d'informations](../references/layers/rewriter.md) sur la syntaxe ainsi que sur l'API à disposition des règles.
2. Testez maintenant à nouveau un appel vers votre proxy:
```shell
