# Cookie Domain List

List of domains, such as `.example.com`, in which cookies have to be set in CDSSO. If this property empty, then the fully qualified domain name of the cookie for the agent server is used to set the cookie domain, meaning that a host cookie rather than a domain cookie is set.

To set the list to `.example.com`, and `.example.net` using the configuration file property, include the following:

`com.sun.identity.agents.config.cdsso.cookie.domain[0]=.example.com`

`com.sun.identity.agents.config.cdsso.cookie.domain[1]=.example.net`

Default: Empty
