+**Intercept Point Note: `REQUEST_BEFORE_EXCHANGE_INIT`**
+
+An interceptor using this intercept point will handle requests before the exchange initialization occurs. Such interceptors must implement the `WildcardInterceptor` interface, ensuring that the `Interceptor.handle(request, response)` method receives both `UninitializedRequest` and `UninitializedResponse` objects.
+
+Additionally, interceptors at this stage may:
+
+- Provide a custom initializer for requests by using `PluginUtils.attachCustomRequestInitializer()`.
+- Modify the raw content of the request using `Request.setRawContent()`.
+
+This setup allows for preliminary modifications and configurations to be applied to requests at an early stage in the processing pipeline.

 == Transforming Request Content Format
 
 Interceptors at `REQUEST_BEFORE_EXCHANGE_INIT` can inspect and modify the request before it is initialized. `The handle(req, res)` and `resolve(req, res)` methods receive the request as `UninitializedRequest` and the response as `UninitializedResponse`. This is particularly useful for transforming request content formats.
