This report summarizes the technical specifications and implementation details for handling cookies within .NET environments, specifically focusing on the 2019 draft standard for attributes and persistent cookie management. 1. SameSite Attribute Implementation

: To delete a cookie, its expiration date must be set to a past date (e.g., DateTime.Now.AddDays(-1) ) and then added back to the Response.Cookies collection.

Managing the persistence and expiration of cookies is critical for maintaining user sessions across application runs.

: Cookies are sent in all contexts but must be marked as Secure .

: No SameSite attribute is sent, leaving the behavior to browser defaults. 2. Cookie Lifecycle and Persistence

The 2019 IETF draft standard for cookies is natively supported in .NET to mitigate Cross-Site Request Forgery (CSRF). Developers can control this through the HttpCookie.SameSite property.

: Cookies are sent on top-level cross-site navigations and first-party requests.

: In modern updates, Session State and Forms Authentication cookies default to SameSite=Lax . Property Values : Strict : Cookies are only sent in a first-party context.
