property CookieManager: TIdCookieManager;

CookieManager is a TIdCookieManager property that enables maintenance of persistent state information using Cookies for the HTTP Client connection. 

CookieManager is accessed when Cookies are detected during processing of headers in an HTTP response, or when preparing headers for an HTTP request. 

CookieManager is used by the HTTP client when AllowCookies contains True. 

The HTTP client ensures that CookieManager is instantiated prior to adding TIdCookieRFC2109 or TIdCookieRFC2965 class instances to the collection maintained in CookieManager. 

CookieManager is freed in the Destroy method.
