Priority fixes for dantri.com.vn
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
Static files cached for 30 days or more
Observed: A same-site stylesheet or script was cacheable for 14 days, short of the 30-day benchmark.
Why it matters: Returning visitors and later page views reuse cached files instead of downloading them again.
What to do: Give versioned (fingerprinted) CSS, JavaScript, fonts and images Cache-Control: public, max-age=31536000, immutable, and change the file name whenever the content changes.
60% of News & Media peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.
Priority 2 · Accelerate
Modern image formats in use
Observed: The homepage had 172 images and none used WebP or AVIF.
What to do: Serve WebP or AVIF with a JPEG or PNG fallback, either through an image CDN or by generating both formats at build time.
44% of News & Media peers do this.

Priority 3 · Harden
DMARC policy enforces quarantine or reject
Observed: No DMARC record was found at _dmarc.dantri.com.vn.
What to do: Publish DMARC with p=none and a reporting address first, fix any legitimate senders that fail SPF or DKIM alignment, then move to quarantine and finally reject.
37% of News & Media peers do this.
Priority 4 · Harden
Framing restricted
Observed: The homepage did not send frame-ancestors or X-Frame-Options, so other sites may frame it.
What to do: Send Content-Security-Policy: frame-ancestors 'self' (or a list of trusted origins). X-Frame-Options: SAMEORIGIN covers older browsers.
42% of News & Media peers do this.
