Frequently Asked Questions
How do I get the Cookie header value?
In Chrome DevTools: open Network tab, click a request, find the 'Cookie' header in the Request Headers section, and copy its value.
What is URL decoding in cookie values?
Cookie values are often URL-encoded (e.g., %3D for =). The decoder column shows the original characters.
Is this the same as Set-Cookie?
No. This parses the Cookie request header (sent by the browser). Set-Cookie is the response header used by servers to create cookies.
