When to use Cookie Parser
Browser requests send a Cookie header containing name and value pairs, while responses use Set-Cookie to attach attributes to individual cookies. Choose the matching mode before parsing a copied header. The output preserves cookie order, duplicate names and values containing equals signs, which helps diagnose sessions with multiple paths or applications sharing the same cookie name.
How to interpret the result
Paste each response cookie on its own line. Commas inside an Expires date are kept intact; combined Set-Cookie headers are not automatically split. Attributes are displayed as written with normalized names, without checking public suffix rules or deciding whether a browser will accept the cookie. Percent escapes are preserved rather than decoded, since cookie values do not have a universal URL-encoding contract.
Example input
Set-Cookie: session=abc=123; Path=/; Secure; HttpOnly; SameSite=Lax
