Configuration

QR Code Generation Strategy:

Easily configure and switch between different QR code generation strategies.

Server Configuration:

HTTP/2 support, server compression, and encoding settings.

Client-Side Caching:

This application also supports client-side caching to improve the performance and load times for static resources.

• Static Resource Caching Static resources, such as stylesheets, scripts, and images, benefit from client-side caching. By setting appropriate cache headers, the browser can store these resources locally, reducing the need to fetch them from the server on subsequent visits.

• Cache Headers:

  • The application is configured to set cache headers for static resources located in the /static path.
  • A cache period of one year is specified to ensure long-term caching, enhancing the user experience by minimizing resource fetching.
