Technical Details

The consent cookie has the following properties:

Property Value
Name sly-consent
Possible values agree or decline
HttpOnly Yes — the cookie is not readable by JavaScript
Secure Yes, when Force HTTPS is set to Entire Site in Global Configuration
SameSite Lax
Path Joomla's Cookie Path setting, or / when it is empty (the default), so one decision covers the whole site
Domain Uses Joomla's configured cookie domain
  1. The visitor clicks Load YouTube or Do not load videos in the consent dialog (the × close button counts as declining)
  2. The form submits a POST request to the current page with the value agree or decline
  3. The plugin validates the CSRF token to prevent tampering
  4. If valid, the consent cookie is set with the configured lifetime
  5. The page reloads with the consent decision applied

Visitors can revoke their consent by clearing their browser cookies. There is no built-in "revoke consent" button — the consent dialog will reappear once the sly-consent cookie is deleted or expires.
