JSON API

Header	Value	Explanation
date	sun, 08 nov 2026 10:02:19 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`.
content-type	text/html; charset=utf-8	The type of the message body, specified as a MIME type.
x-powered-by	php/8.5.12	Some of the software used to generate or serve this page. Warning Sharing too many details about a server or web application makes it easier for hackers to target a website. Avoid specific version numbers such as 8.5.12, especially when running software that is end-of-life and/or has known security bugs. Consider removing this header. At a minimum, remove any version number.
x-dns-prefetch-control	on	DNS requests are very small in terms of bandwidth, but latency can be quite high. Prefetching DNS results can significantly improve page load performance. Notice This feature is non-standard and is not on a standards track. Not supported by all browsers.
link	<https://cdn.gtranslate.net/>; rel=dns-prefetch	`rel="dns-prefetch"` tells the browser to resolve the domain name of the specified host ahead of time. This saves time later when the browser needs to actually connect to that host. Unlike `preconnect`, this only performs DNS lookup; it does not open a connection.
link	<https://yootimes.tech/wp-json/>; rel="https://api.w.org/"	`rel="https://api.w.org/"` is where you can learn more about WordPress' REST API. Applications can interact with this WordPress site by sending and receiving JSON objects.
link	<https://yootimes.tech/wp-json/wp/v2/pages/23401>; rel="alternate"; title="json"; type="application/json"	`rel="alternate"` specifies an alternate version of the current page, often using a different language (`hreflang` attribute), a different MIME type (`type` attribute) or a different media format (`media` attribute).
link	<https://yootimes.tech/>; rel=shortlink	`rel="shortlink"` specifies a shorter URL for the current page, to be used in space-constrained interfaces or for manual entry.
etag	"947-1794096642;br"	A unique identifier that changes every time a page at a given URL changes. It acts as a fingerprint. A cache can compare `ETag` values to see if the page has changed and has become stale. For example, a browser will send the `ETag` value of a cached page in an `If-None-Match` header. The web server compares the `ETag` value sent by the browser with the `ETag` value of the current version of the page. If both values are the same, the web server sends back a `304 Not Modified` status and no body.
x-litespeed-cache	hit	The page was served from LiteSpeed's cache.
content-encoding	br	Specifies how the resource is compressed. Not to be confused with `Transfer-Encoding` which specifies how the data is transferred. `br` means that the data is compressed with `brotli`. Warning Add a `Content-Length` header. The Content-Length header is required, unless the message is transported using chunked encoding. Without a `Content-Length` header some servers will respond with 400 (bad request) or terminate connections early.
platform	hostinger	Some of the software used to generate or serve this page.
panel	hpanel
content-security-policy	upgrade-insecure-requests	The Content Security Policy (CSP) header helps prevent cross-site scripting (XSS), clickjacking, and other code injection attacks by specifying which dynamic resources are allowed to load. `upgrade-insecure-requests` instructs browsers to replace insecure URLs (HTTP) with secure URLs (HTTPS). Notice No `default-src` directive is set. Without it, directives that are not explicitly defined have no fallback restriction. Notice Consider adding `base-uri 'self'` or `base-uri 'none'` to prevent base tag injection, which can redirect relative URLs to an attacker-controlled domain.
age	27047	The time in seconds that the page has been in the shared proxy cache. The maximum age is set by `max-age` or `s-maxage` in the `Cache-Control` header.
vary	accept-encoding	The `Vary` header specifies a list of headers that must be considered when caching responses. For a cached response to be used, these headers must match between the cached response and the new request. This ensures that the appropriate version of a resource is served based on factors like language, encoding, or device type.
server	hcdn	Identifies the software used by the origin server to handle the request (e.g. Apache, Nginx, Cloudflare). Notice Consider removing or minimizing the `Server` header. Even without a version number, it reveals the server software, which aids reconnaissance.
alt-svc	h3=":443"; ma=86400	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=86400` specifies that the alternative service information is fresh for 86400 seconds.
x-hcdn-request-id	a1212bd78f0361784f041f9de9e92044-imm-edge7	A unique request identifier generated by Hetzner CDN.
x-hcdn-cache-status	hit	Indicates how Hetzner CDN processed this request. Common values: `hit` (served from cache), `miss` (fetched from origin).
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.
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.
cross-origin-resource-policy		missing Add a `Cross-Origin-Resource-Policy` header. It controls which origins can embed or load this page's resources (images, scripts, etc.), preventing hotlinking and cross-origin data leaks.
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.
