My google engine java app looses all user data when user request is redirected to the new instance :
"This request caused a new process to be started for your application, and thus caused your application code to be loaded for the first time. This request may thus take longer and use more CPU than a typical request for your application."
as it is quite inconvenient behaviour i tried to set-up one resident instance so i setted "Idle Instances" to 1-1 but this does not solve my problem i am getting one resident instance and always there`s new (dynamic) instance created which serves some requests... (this guy have the same problem : Why GAE launched a second instance with Max Idle Instances set to 1)
I dont want to use dynamic instances at all (my app have always low load, not many users). I need to serve only one resident instance to the users. Is that possible to set in GAE ? If not , is there any convinient and reliable way how to save data between pages (e.g. store them in datastore ?). I am passing a lot of POST parameters between pages.
