Files cached for 1 week for testing
Use the API endpoint: POST /file-upload-api for programmatic testing.
How it works. Files are uploaded as sequential 8 MB chunks, then served back from the Cloudflare edge cache. No chunk ever exceeds the request-body limit, so Safari no longer crashes on large files. Up to ~90 MB per file. Download links are warmed into the CDN cache automatically and stay valid until the cache expires.
