Stateless vs Stateful
Transcript of Stateless vs Stateful
Each interaction is handled based on the information available for that interaction Examples:
Internet Protocol (IP)
Hyper Text Transfer Protocol Advantages:
Reduces memory usage
Reduces session expiration issues Disadvantages:
Harder to maintain user interaction and create a seamless web application.
May require extra information to be sent to and from a client. STATEFUL Opposite to stateless
Keeps track of the state of interaction Example:
State is sent and returned in HTTP headers. Allows data (User information, search criteria) to be maintained between web requests. Advantages:
Keep track of a user throughout a web application/site
More intuitive - Entity data can be maintained on the server between requests.
Can sometimes improve performance when retrieval of data is only required once. Disadvantages:
Requires memory to be allocated to store the data.
Can lead to a performance decrease if session storage is not maintained efficiently.
