9 missing headers, 2 warnings, 2 notices
JSON API

Header	Value	Explanation
cross-origin-resource-policy	cross-origin	Controls which origins are allowed to load this resource (e.g. embed this image, load this script). This prevents other sites from hotlinking your resources and is how a resource signals its consent to be loaded by pages that use `Cross-Origin-Embedder-Policy`. Notice `cross-origin` means the resource can be loaded by documents from any origin. This is the least secure option.
content-type	text/html; charset=utf-8	The type of the message body, specified as a MIME type.
date	sun, 25 oct 2026 15:59:34 gmt	The date and time at which the request was made. A browser uses it for age calculations rather than using its own internal date and time; e.g. when comparing against `Max-Age` or `Expires`.
server	blogger render server 1.0	Identifies the software used by the origin server to handle the request (e.g. Apache, Nginx, Cloudflare). Warning The server header exposes a version number (1.0). This makes it easier for attackers to find known vulnerabilities for that version. Remove or suppress the version number.
content-length	141	The size of the message body, in bytes.
x-xss-protection	0	A legacy header that enables the browser's built-in cross-site scripting (XSS) filter. Modern browsers ignore it in favor of `Content-Security-Policy`. Warning `0` disables XSS filtering. Remove this header or set the value to `1`. Notice Add a `Content-Security-Policy` header for more comprehensive protection.
x-frame-options	sameorigin	`X-Frame-Options` prevents this URL from being embedded in an `iframe`. This protects against clickjacking attacks. `sameorigin` allows this page to be displayed in an `iframe` on the same origin. This is the recommended setting.
alt-svc	h3=":443"; ma=2592000,h3-29=":443"; ma=2592000	The `alt-svc` header tells the browser that the same content is available over a different protocol. This allows the browser to upgrade to a faster protocol (e.g. HTTP/3 over QUIC) on subsequent requests without a separate negotiation step. `h3` indicates that HTTP/3 is supported. HTTP/3 uses the QUIC protocol (UDP-based) instead of TCP, which eliminates the TCP handshake delay and performs better on lossy networks. Variants like `h3-29` refer to specific drafts of the HTTP/3 protocol. `ma=2592000` specifies that the alternative service information is fresh for 2592000 seconds. `ma=2592000` specifies that the alternative service information is fresh for 2592000 seconds.
strict-transport-security		missing Add a `Strict-Transport-Security` header. The `Strict-Transport-Security` header or HSTS header is used to instruct browsers to only use HTTPS, instead of using HTTP. It helps enforce secure communication.
content-security-policy		missing Add a `Content-Security-Policy` header. The `Content-Security-Policy` header helps browsers prevent cross site scripting (XSS) and data injection attacks.
referrer-policy		missing Add a `Referrer-Policy` header. When a visitor navigates from one page to another, browsers often pass along referrer information. The `Referrer-Policy` header controls how much referrer information a browser can share. This is important to configure when private information is embedded in the path or query string and passed onto an external destination.
permissions-policy		missing Add a `Permissions-Policy` header. Restrict access to device features like the camera, microphone, location, accelerometer and much more.
cross-origin-embedder-policy		missing Add a `Cross-Origin-Embedder-Policy` header. It requires cross-origin resources to explicitly consent before this page can load them, protecting those resources from being exposed to Spectre-style timing attacks. Together with `Cross-Origin-Opener-Policy`, it enables cross-origin isolation and access to `SharedArrayBuffer`.
cross-origin-opener-policy		missing Add a `Cross-Origin-Opener-Policy` header. It prevents other sites from retaining a `window` reference to this page when opened via `window.open()` or navigation, blocking script-based attacks through shared browsing contexts.
x-content-type-options		missing Add an `X-Content-Type-Options: nosniff` header to prevent browsers from MIME type sniffing. Without it, browsers may interpret files as a different content type than intended, which can lead to security vulnerabilities.
x-permitted-cross-domain-policies		missing Add a `X-Permitted-Cross-Domain-Policies` header to prevent Flash, Adobe Reader and other clients from sharing data across domains.
content-encoding		missing No `Content-Encoding` header found. Enable compression such as `gzip` or `br` (Brotli) to reduce transfer sizes. Brotli typically achieves 15–20% better compression than gzip and is supported by all modern browsers.
