Priority fixes for virtualdj.com
Ordered by impact and by how common each practice is among peers.
Priority 1 · Harden
HTTP requests move to HTTPS
Observed: A request to http://virtualdj.com/ 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 Programming & Software peers do this. Limit: Measured for the homepage only, from one location, at the time of the check.
Priority 2 · Accelerate
HTML compressed
Observed: The homepage HTML (65 KB) was delivered without gzip, Brotli or zstd compression.
What to do: Enable Brotli or gzip for text responses (HTML, CSS, JavaScript, JSON, SVG) at the CDN or origin.
On Amazon CloudFront: Enable Compress objects automatically on the cache behaviour.
94% of Programming & Software peers do this.

Priority 3 · 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.
40% of Programming & Software peers do this.
Priority 4 · Enable
XML sitemap discoverable
Observed: No sitemap was listed in robots.txt or found at /sitemap.xml.
What to do: Generate an XML sitemap of canonical URLs, reference it in robots.txt and submit it in Google Search Console.
69% of Programming & Software peers do this.
