README.md

README.md 是项目的说明文档，包含了项目的简介、安装、配置和使用方法。以下是部分内容：

# Apache Sling Dynamic Include

This module introduces a Servlet Filter that replaces dynamic components (e.g., current time or foreign exchange rates) with server-side include tags (e.g., SSI or ESI). Thanks to this approach, the whole page can be cached by the Dispatcher or a Content Delivery Network while dynamic components are still updated in real-time.

## Installation

To install and use Apache Sling Dynamic Include, follow these steps:

1. Clone the repository:
    ```sh
    git clone https://github.com/apache/sling-org-apache-sling-dynamic-include.git
    ```
2. Build the project using Maven:
    ```sh
    mvn clean install
    ```
3. Deploy the generated bundle to your Sling instance.

## Configuration

To configure Apache Sling Dynamic Include, you need to set up the following parameters in your OSGi console:

- `include.type`: The type of include to use (e.g., SSI, ESI).
- `include.path`: The path to the
