|
| 894. |
What is the constraint on the data per cookie?(a) 2 KB(b) 1 KB(c) 4 KB(d) 3 KB |
|
Answer» Correct choice is (c) 4 KB The best I can explain: Each cookie can hold up to only 4 KB. In practice, browsers allow many more than 300 cookies total, but the 4 KB size limit may still be enforced by some. Storage of a session has to be a minimum of 5MB. |
|
| 895. |
Which of the following is a Boolean cookie attribute?(a) Bool(b) Secure(c) Lookup(d) Domain |
|
Answer» Right choice is (b) Secure The best explanation: The final cookie attribute is a boolean attribute named secure that specifies how cookie values are transmitted over the network. By default, cookies are insecure, which means that they are transmitted over a normal, insecure HTTP connection. If a cookie is marked secure, however, it is transmitted only when the browser and server are connected via HTTPS or another secure protocol. |
