Priority fixes for 4download.net

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

1. Priority 1 · Harden

   HSTS kept for at least a year

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

   Why it matters: HSTS tells browsers to use HTTPS for your host on every later visit, which removes the window where a first HTTP request can be intercepted.

   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 Blogger: 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.

   40% of Programming & Software peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

2. Priority 2 · 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 Blogger: 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.

3. Priority 3 · Accelerate

   HTTP/3 advertised

   Observed: The homepage did not advertise HTTP/3 through an Alt-Svc header.

   What to do: Turn on HTTP/3 at your CDN. Browsers fall back to HTTP/2 automatically, so the risk is low.

   On Blogger: 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 · Harden

   Content Security Policy present

   Observed: The homepage response did not include a Content-Security-Policy header.

   What to do: Start with Content-Security-Policy-Report-Only to see what would break, tighten the policy over a few weeks, then enforce it.

   On Blogger: 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.
