The writeSecureCookies variable allows AppMeasurement to set Secure cookies for Analytics. This setting applies to both visitor ID cookies set by AppMeasurement, and cookies you set using the Util.CookieWrite() method. It requires AppMeasurement 2.18.0 or higher.

writeSecureCookies applies only to cookies set by AppMeasurement JavaScript (s_fid, s_cc and s_sq). Cookies set by https response (s_vi and s_ecid) can be set to ‘secure’ by contacting Adobe Customer Care.

If you enable the writeSecureCookies variable, make sure that all content on your site is served securely over HTTPS. AppMeasurement does not work if this variable is enabled and you have insecure content on your page.

The s.writeSecureCookies variable is a boolean that determines if AppMeasurement sets the Secure attribute when creating a cookie. Its default value is false.
