public bool ResponseWithNoExpiryInformationIsFresh { get; set; }

Field Value

true if a response with no expiry information is considered to be fresh; otherwise, false.

Usually, a response from a web server will have an "Expires" header, which gives the date/time after which the response is considered stale. However, if a response does not contain any expiry information, then it is up to the browser to decide whether or not a response should be considered fresh or not. Most browsers wil consider the response to be stale, and so will re-request it from the server. However, there may be cases where you want th opposite behaviour (i.e. consider the response to be fresh and so do not re-request it). This can be achieved by setting this property to true. The default value for this property is false.
