Express security middleware used by 울집마켓 and Kithub.

• Security: Enhance security by setting HTTP headers, managing CORS (Cross-Origin Resource Sharing), preventing CSRF (Cross-Site Request Forgery), and other security-related measures.

• Error Handling: Implement features to handle unexpected exceptions or errors and provide user-friendly error messages to enhance stability.

• Request Data Validation: Validate incoming request data and filter out invalid data using middleware to ensure data integrity.

• Caching: Implement caching to store frequently used data or API responses, optimizing server response time.

• Rate Limiting: Add functionality to limit the rate of incoming requests to prevent overload and ensure server stability.

• Session Management: Manage and maintain sessions to track and preserve user states throughout their interactions with the application.

• Data Compression: Reduce network traffic by compressing response data before sending it to clients.
