Answer from AI
The browser can cache various types of resources and data to speed up page loading:
- HTML documents
- CSS files
- JavaScript scripts
- Images (JPEG, PNG, SVG, etc.)
- Fonts
- API responses (e.g., JSON), if caching headers are set
Caching is based on HTTP headers such as Cache-Control, ETag, and Last-Modified, which allow the browser to reuse stored resources without making a new request to the server.
