Cache-Control Headers Set Incorrectly
After Cursor refactored your server response headers, caching is not working correctly. Either assets are cached too long (users see stale content) or not cached at all (every request hits server).
Cache-Control headers were changed incorrectly.
Error Messages You Might See
Users see stale content
Every request hits server
Cache not being used
Assets downloaded repeatedly
Common Causes
- Cache-Control header removed entirely
- Max-age set to 0, disabling all caching
- No-cache or no-store applied to static assets
- Immutable directive removed from versioned assets
- Different headers applied to HTML vs CSS/JS
How to Fix It
Static assets (hashed): Cache-Control: max-age=31536000, immutable. HTML: max-age=0, no-cache (always revalidate). API: appropriate based on data freshness. Use ETag for validation. Test with DevTools Network tab.

’m a Senior Full-Stack Developer and Tech Lead with experience designing and building scalable web platforms. I work across the full development lifecycle, from translating business requirements into technical architecture to delivering reliable production systems.
My work focuses on modern web technologies, including TypeScript, Angular, Node.js, and cloud-based architectures. I enjoy solving complex technical problems and helping teams turn product ideas and prototypes into working platforms that can grow and scale.
In addition to development, I often collaborate closely with product managers, business analysts, designers, and QA teams to ensure that solutions align with both technical and business goals.
I enjoy working with startups and product teams where I can contribute both as a hands-on engineer and as a technical partner in designing and delivering impactful software.

Cursor ambassador and agentic tooling builder.
I've scaled systems, automated deployments, and built observability tools for AI coding workflows. I specialize in taking vibe-coded apps from broken prototype to production-ready: fixing Supabase auth/RLS, Stripe integrations, deployment pipelines, and cleaning up AI-generated spaghetti.
I build tools in this space (agentprobe, claudebin, micode) and understand both sides: how AI generates code and why it breaks.

You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.

How do I cache bust versioned assets?
Use content hash in filename (app.abc123.js). Set long max-age. HTML loads correct version number.
What's the difference between cache-control directives?
no-cache: revalidate before use. no-store: don't cache. max-age: seconds to cache. immutable: never changes.
