MDN’s new design is in Beta! A sneak peek:

The Cookie HTTP request header contains stored HTTP cookies previously sent by the server with the Set-Cookie header.

The Cookie header might be omitted entirely, if the privacy setting of the browser are set to block them, for example.

Header type Request header
Forbidden header name yes


Cookie: <cookie-list>
Cookie: name=value
Cookie: name=value; name2=value2; name3=value3
A list of name-value pairs in the form of <cookie-name>=<cookie-value>. Pairs in the list are separated by a semi-colon and a space ('; ').


Cookie: PHPSESSID=298zf09hf012fh2; csrftoken=u32t4o3tb3gg43; _gat=1;


Specification Title
RFC 6265, section 5.4: Cookie HTTP State Management Mechanism
