We are moving forward with 4D v16 on preemptive multi-threading as the 4D Web Server is also becoming preemptive. Just click one checkbox and your application will support more simultaneously connected users, and process more requests in parallel. For requests using a lot of CPU time, execution can be up to 2 times faster!
The WEB Session commands have been adapted to 4D Mobile session. Now, you can save the results of a query or an inter-process variable related to a given 4D Mobile session. For example, with new handling of 4D Mobile sessions, you can manage the cart of your users.
