This setting specifies the URL to which a SMART on FHIR launch is only allowed.
For example, if a SMART on FHIR launch is only allowed to access the patient overview layout, where the application name of the Clinician Window UI is CW_UI in IIS, your domain is my.domain, your machine name is MedStaff1, and the environment is configured for secure connections, then the value is:
"BaseRedirectUrlCookiePathOption": "https://MedStaff1.my.domain/CW_UI/overview",
Once this value is configured, any SMART on FHIR launches attempting to access any other URL other than the one configured will fail and instead redirect to logging in via IdP. If this setting is not configured and the value is empty, SMART on FHIR launches will not be allowed to all URLs.
