In Destination Builder, the Configuration section contains the Cookie Domain and Publish Data To fields. These let you create rules to determine if a destination sets a cookie or returns a cookie. Cookie Domain and Publish Data To work independently of each other and are optional. You can create a cookie destination without using either of them.
Cookie Domain: Syntax and Examples
Cookie Domain
Description
Syntax
The Cookie Domain field accepts a simple text string that lets you set cookies on a specified domain or all domains. When using this feature:
Set only one domain for each cookie destination. Do not type multiple domains in the Cookie Domain field. Create another Destination instead.
Do not use wildcard characters.
Leave the Cookie Domain field blank to set a cookie on all domains. This is the default setting.
To set cookies on a specific domain and sub-domains:
Type the name of the domain in the Cookie Domain field.
Start the domain name with a period. For example, .somedomain.com.
The https://www prefix is not required.
Example
As a simple example, let's say we have a fictitious site called sports.com. Sports.com has domains for golf, baseball, and football. To set a cookie in all the sports domains, you would type that in the Cookie Domain box as shown below:
This tells Audience Manager to set a cookie in any domain that contains the pattern something.sports.com. See below for a more complex set of examples.
Complex Cookie Domain Examples
These examples show you if Audience Manager will set a cookie based on how the Cookie Domain option is configured.

Only the selected domains: Returns a cookie only for the domains selected in the domains list.
All of our domains except the selected domains: Prevents selected domains from receiving a cookie. All other domains can receive a cookie.
