How can you manually clear the cache in a CDN system?

The following methods are commonly used for manual cache clearing in CDN systems:

• Through the CDN provider's control panel: there is an option "Purge" or "Invalidate" that allows you to delete cached files by URL or for the entire site.
• Via CDN API: many providers offer REST APIs for programmatic cache clearing.
• Using command line or specialized utilities if the CDN supports such tools.

For example, in Cloudflare, you can clear the cache through their web interface by selecting "Caching" → "Purge Cache" and specifying the desired URLs or clearing the entire cache.
