SetCookieoverskrift

SetCookieoverskrift is a Danish term used in web development to refer to the HTTP response header Set-Cookie. It describes the mechanism by which a server instructs a client to store a cookie and return it with subsequent requests to the same origin. The term is primarily encountered in Danish documentation and tutorials.

A cookie is defined as a name-value pair, optionally followed by attributes that control its behavior. The Set-Cookie header can carry one cookie per header, with optional attributes such as Expires or Max-Age, Domain, Path, Secure, HttpOnly, and SameSite. Multiple cookies can be set by sending multiple Set-Cookie headers in the same response.

Example in plain language: Set-Cookie: sessionId=abc123; HttpOnly; Secure; SameSite=Strict. This instructs the browser to store a sessionId cookie that is only sent over secure connections, is inaccessible to client-side scripts, and is restricted in cross-site contexts.

Uses and considerations: cookies support session management, personalization, and tracking. For security and privacy, developers should set HttpOnly to protect against cross-site scripting, Secure to require HTTPS, and SameSite to mitigate cross-site request forgery. There are limits on cookie size and the number of cookies per domain, and many browsers limit total header sizes.

Notes: The name SetCookieoverskrift is not an official standard; it is a descriptive term used in Danish sources to talk about the Set-Cookie header rather than a formally defined header name. See also Set-Cookie header, HTTP cookie, SameSite, HttpOnly, Secure.
