Header
Value
Explanation
date
sun, 22 dec 2024 12:38:39 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.
content-length
12394
The size of the message body, in bytes.
server
nginx/1.13.4
content-language
en
Specifies the page's intended audience. For example, en-US means that the document is intended for English language speakers in the United States. The language tags are defined in RFC 5646.
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 to specify how this page can be loaded by cross-origin resources.
cross-origin-opener-policy
missing Add a Cross-Origin-Opener-Policy header to opt-in into better browser isolation.
cross-origin-resource-policy
missing Add a Cross-Origin-Resource-Policy header to specify who can load this page.
x-frame-options
missing Add a X-Frame-Options header. The X-Frame-Options header prevents this URL from being embedded in an iframe. This protects against clickjacking attacks. Alternatively, set a Content-Security-Policy header with a frame-ancestor directive.
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.
