- Browser-based RSS readers like Blogs Are Back fetch feeds directly in the browser, bypassing third-party servers.
- Browsers block cross-origin requests by default, requiring CORS headers like 'Access-Control-Allow-Origin: *' for compatibility.
- Direct fetching is faster, eliminates proxy dependencies, and reduces hops between blogs and readers.
- To verify CORS, use browser developer tools or curl to check headers and test fetch requests.
- Common CORS issues include misconfiguration, unhandled OPTIONS requests, or CDN caching problems—fixes involve redeploying and clearing caches.
