Does the ASP.NET_SessionId cookie need consent?

Usually not. ASP.NET_SessionId is in the Essential category, and strictly necessary cookies are exempt from consent under the ePrivacy Directive and PECR. It must still be listed in your cookie policy.

How long does the ASP.NET_SessionId cookie last?

ASP.NET_SessionId usually lasts until the browser closes. The exact lifetime depends on the site's settings and the version of the script that sets it.

Who sets the ASP.NET_SessionId cookie?

ASP.NET_SessionId is set by ASP.NET. It is in the Essential category.

How do I block or delete the ASP.NET_SessionId cookie?

Visitors can delete ASP.NET_SessionId in their browser's cookie settings, although the website may not work properly without it. A consent banner lists it under Essential, which is always active, so it is not blocked.

Consent

Usually not needed

ASP.NET_SessionId is in the Essential category. Strictly necessary cookies are exempt from consent under Article 5(3) of the ePrivacy Directive, as long as the cookie is really needed for the service the visitor asked for. It still belongs in your cookie policy.

GDPR and ePrivacy (EU): Exempt from prior consent under the strictly necessary exemption (Article 5(3) of the ePrivacy Directive), as long as ASP.NET_SessionId is really needed for the service the visitor asked for. It must still be listed in your cookie policy.
UK GDPR and PECR: Exempt from consent under PECR Regulation 6(4) when strictly necessary. It must still be listed in your cookie policy.
CCPA and CPRA (California): No opt-out is needed for a strictly necessary cookie, but ASP.NET_SessionId must be disclosed in your privacy policy.

Managing ASP.NET_SessionId with a consent banner

A consent banner lists ASP.NET_SessionId in its cookie table under Essential, the category that is always active. Because it is strictly necessary, it works without an opt-in, and listing it keeps your cookie policy accurate. Kukie.io's cookie scanner finds it when it scans your website.
