Priority fixes for weathernews.jp

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

1. Priority 1 · Harden

   HTTP requests move to HTTPS

   Observed: A request to http://weathernews.jp/ was not redirected to HTTPS.

   Why it matters: Visitors who type the address or follow an old link start on unencrypted HTTP. A redirect moves them to the encrypted site before any cookies or form data are sent.

   What to do: Add a permanent (301 or 308) redirect from every http:// URL to the same https:// URL at your CDN, load balancer or web server.

   On Amazon CloudFront: Set the viewer protocol policy of each cache behaviour to Redirect HTTP to HTTPS.

   92% of Weather Forecast peers do this. Limit: Measured for the homepage only, from one location, at the time of the check.

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.

3. Priority 3 · Accelerate

   Static files cached for 30 days or more

   Observed: A same-site stylesheet or script was cacheable for no max-age, short of the 30-day benchmark.

   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.

   On Shopify: this setting is largely controlled by the platform. Check the platform's settings and documentation, or ask its support team whether it can be changed for your domain.

4. Priority 4 · Enable

   66% of Weather Forecast peers do this.
