Priority fixes for astrotheme.fr
Ordered by impact and by how common each practice is among peers.
Priority 1 · Accelerate
HTML compressed
Observed: The homepage HTML (191 KB) was delivered without gzip, Brotli or zstd compression.
Why it matters: Compression usually shrinks HTML several times over, so the first bytes of the page arrive sooner on slow connections.
What to do: Enable Brotli or gzip for text responses (HTML, CSS, JavaScript, JSON, SVG) at the CDN or origin.
92% of Uncategorized peers do this. Limit: Read from the homepage response only; other pages or regions may send different headers.

Priority 2 · Accelerate
HTTP/2 negotiated
Observed: The TLS handshake selected HTTP/1.1 instead of HTTP/2.
What to do: Enable HTTP/2 on your CDN or server. Most CDNs do this by default.
87% of Uncategorized peers do this.
Priority 3 · Harden
TLS 1.3 negotiated
Observed: The TLS connection negotiated TLSv1.2.
What to do: Enable TLS 1.3 on your CDN or server. Keep TLS 1.2 available for older clients unless you have checked your audience.
90% of Uncategorized peers do this.
Priority 4 · 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.
34% of Uncategorized peers do this.
