+#### (4) From HTTP requests
+In order to setup an automatic bound from HTTP requests to API directly, you must use a **router**.
 
-**Case 1**: You want an URL like `http://www.host.com/{module}/{method}/` and pass parameters through POST or form-data. In order to set it up, you must catch the url starting at `/{module}/{method}` so you have to truncate the beginning (for instance if you have /api/{module}/..)
+
+> ##### 1) Format url so it must begin with `/{module}/{method}`
+
+```php
+<?php
+	
+	...
+
+	// let's suppose the url is `/api/{module}/{method}`
+	$url = '/api/somemodule/somemethod/1/2/';
+	$url = substr($url, strlen('/api'));
+```
+
+> ##### 2) give the url to the HTTP manager
+
+```php
+<?php
+	
+	...
+	
+	// create request from HTTP data
+	$request = Request::remote($url);
+
+	// manage request error
+	if( $request->error->get() !== Err::Success )
+		die('request error');
+
+	// execute request and catch response
+	$response = $request->dispatch();
+
+	// return response as HTTP body
+	die( $response->serialize() );
+```
+
+
+
+Then can handle various kinds of URL :
+> 1. `http://www.host.com/{module}/{method}/`
+- parameters can be in URL (separated by `/`)
+- parameters can be in `multipart/form-data` or `x-www-form-urlencoded`
+- parameters of both URL and content are caught
+
+> 2. `http://www.host.com/api/{module}/{method}/`
+- parameters can be in URL (separated by `/`)
+- parameters can be in `multipart/form-data` or `x-www-form-urlencoded`
+- parameters of both URL and content are caught
+
+> 3. `http://www.host.com/`
+
+
+> 4. `https://www.host.com/api/`
 
 **Case 2**: You want an URL like `http://www.host.com/api/` and pass all data through POST or form-data.
