Priority fixes for swisstransfer.com

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

1. Priority 1 · Accelerate

   No render-blocking scripts in <head>

   Observed: The homepage <head> loaded 1 external script without async or defer.

   Why it matters: A plain <script src> in the head stops the browser from showing anything until that file has downloaded and run.

   What to do: Add defer to scripts that need the DOM, async to independent ones such as analytics, or move them to the end of the body.

   56% of Cloud Storage & File Transfer peers do this. Limit: Based on the homepage HTML delivered to an automated client; scripts that run later were not executed.

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.

   35% of Cloud Storage & File Transfer peers do this.

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.

   44% of Cloud Storage & File Transfer peers do this.

4. Priority 4 · Harden

   X-Content-Type-Options: nosniff

   Observed: The homepage response did not include X-Content-Type-Options: nosniff.

   What to do: Send X-Content-Type-Options: nosniff on all responses and make sure each file is served with the correct Content-Type.

   52% of Cloud Storage & File Transfer peers do this.
