|On object||TMLUserProfile "profile"|
Marks this profile as being allowed for persistent storage
This property is necessary only when using personalisation mode "Automatic / Cookie based" plus the feature to opt-in profile storage. After the user has been presented a UI, asking for the opt-in, this method should be called if the user confirmed its approval for persistent profile storage. The profile from this on will behave like a normal persisted profile. Also the WGPID cookie will now be sent to the user so he returns to the same profile on later HTTP sessions.
