HTTP Caching

Action

no-store (uncacheable)

FIX

no-store (uncacheable)

Cache-Control: no-store prevents all caching

Intentional for dynamic content, but increases server load for every page view.

Got: no-store, no-cache, must-revalidate

No ETag or Last-Modified header

Conditional requests (304 Not Modified) are not possible without validators.

Cache-Control

no-store, no-cache, must-revalidate

Directive	Value	Meaning
no-store	—	Never cache this response
no-cache	—	Cache but always revalidate first
must-revalidate	—	Must recheck with server after expiry

Image Optimization

6 images, 0 KB saveable

REVIEW

6 images, 0 KB saveable

https://daralsharka.online/assets/images/logo-icon... is missing width/height — may cause layout shift

Set explicit width and height to prevent CLS.

6 images 726 KB

0 oversized -0 KB

5 legacy format

1 missing dimensions CLS risk

Set explicit width and height to prevent CLS.

Why this matters

Image without explicit width/height — browser can't reserve space; CLS jumps when image loads.

Server-Timing Observability

No Server-Timing header found

REVIEW

No Server-Timing header found

Server-Timing exposes backend timing breakdowns to browser DevTools (e.g., `db: 45ms; render: 120ms; cache: 2ms`). Useful for diagnosing slow pages without backend log access. Most modern frameworks (Next.js, Cloudflare Workers, Fastly) emit it automatically; absence on a managed platform usually means telemetry headers are stripped at the edge.
