Priority fixes for vagalume.com.br

Ordered by impact and by how common each practice is among peers.

1. Priority 1 · Accelerate

   Static files cached for 30 days or more

   Observed: A same-site stylesheet or script was cacheable for 3 hours, 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.

   56% of Audio & Music Streaming peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · Harden

   HSTS kept for at least a year

   Observed: The homepage response did not include a Strict-Transport-Security header.

   What to do: Send Strict-Transport-Security on HTTPS responses. Start with a short max-age (for example 300 seconds), confirm every subdomain works over HTTPS, then raise it in steps to 31536000. Add includeSubDomains only when all subdomains are HTTPS. HSTS preload is optional and hard to undo; hstspreload.org itself does not recommend it by default.

   On Amazon CloudFront: Attach a response headers policy with Strict-Transport-Security to each distribution.

   33% of Audio & Music Streaming peers do this.

3. Priority 3 · 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.

   On Amazon CloudFront: Set frame options in a response headers policy.

   42% of Audio & Music Streaming peers do this.

4. Priority 4 · Harden

   Certificate lifetime of 100 days or less

   Observed: The certificate from Amazon had a 394-day validity period, longer than the 100-day maximum that applies from March 2027.

   What to do: Move to automated issuance and renewal now, while you still have time to test it.

   69% of Audio & Music Streaming peers do this.
