fpCookieDomainPeriods variable helps AppMeasurement determine where Analytics cookies are set by calling out that the domain suffix has an extra period in it. This variable allows AppMeasurement to accommodate the extra period in the domain suffix and set cookies in the right location. It inherits the value of
cookieDomainPeriods, but is still a best practice to set if you use a first-party cookie implementation.
www.example.com, this variable does not need to be set. If needed, you can set this variable to
www.example.co.jp, set this variable to
Do not take subdomains into account for this variable. For example, do not set
fpCookieDomainPeriods on the example URL
store.toys.example.com. AppMeasurement by default recognizes that cookies should be stored on
example.com, even on URLs with many subdomains.
The Web SDK can determine the correct cookie storage domain without this variable.
First-party Domain Periods is a field under the Cookies accordion when configuring the Adobe Analytics extension.
Set this field to
3 only on domains containing a period in its suffix. Otherwise this field can be left blank.
fpCookieDomainPeriods variable is a string that is typically set to
"3", only on domains that contain a period in its suffix. Its default value is
"2", which accommodates most domains.
// Manually set fpCookieDomainPeriods for domains with a period in its suffix, such as www.example.co.uk s.fpCookieDomainPeriods = "3"; // Detect if a URL has a domain suffix with an extra period, and set s.fpCookieDomainPeriods automatically document.URL.indexOf(".co.") > 0 ? s.fpCookieDomainPeriods = "3" : s.fpCookieDomainPeriods = "2";
