Parse a Cookie header

Cookie request headers can become long and hard to inspect during debugging. Paste the Cookie header value to split it into readable name and value pairs and see header size. It is useful for browser debugging, support escalations, auth QA, analytics cleanup and performance reviews.

Keep cookie headers small because they are sent with matching requests.
