This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
Do not store large object graphs inside an HttpSession: If you store the data in the HttpSession as one large object graph, the application server will have to process the entire HttpSession object each time. This forces Java serialization and adds computational overhead. The throughput decreases as the size of the objects stored in the HttpSession increases because of the serialization cost.
I just want to know how Java serialization and adds computational overhead happens? what is serialization cost.
