project object for each application running on the server.project object when an application starts and destroys the project object when the application or server stops. The typical project object lifetime is days or weeks.
Each client accessing the same application shares the same project object. Use the project object to maintain global data for an entire application. Many clients can access an application simultaneously, and the project object lets these clients share information.
You can lock the project object to ensure that different clients do not change its properties simultaneously. When one client locks the project object, other clients must wait before they can lock it. See Lock for more information about locking the project object.

lastID property and assigns a value to it by incrementing an existing value.project.lastID = 1 + parseInt(project.lastID, 10)Example 2. This example increments the value of the
lastID property and uses it to assign a value to the customerID property.project.lock()In the previous example, notice that the
project.lastID = 1 + parseInt(project.lastID, 10);
client.customerID = project.lastID;
project.unlock();
project object is locked while the customerID property is assigned, so no other client can attempt to change the lastID property at the same time.client, request, server project object has no predefined properties. You create custom properties to contain project-specific data that is required by an application.
You can create a property for the project object by assigning it a name and a value. For example, you can create a project object property to keep track of the next available Customer ID. Any client that accesses the application without a Customer ID is sequentially assigned one, and the value of the ID is incremented for each initial access.
