Avoid unnecessary Ajax traffic with session state
Author: JT Smith
Where possible, creating Web applications Ã¢â¬â including Ajax-based applications Ã¢â¬â in a RESTful way avoids a large class of bugs. However, a pitfall of REST is sending duplicate data across similar XMLHttpRequests. This tip shows how the moderate use of session cookies can maintain just enough server-side state to significantly reduce client-server traffic, while still allowing fallback to cookie-free operation.
