Web Application Client Cache (WACC) is a generic application model that enables more interactive, more responsive, and smarter Web applications by moving from traditional "click, wait, and refresh" user interaction model to "Partial screen update" paradigm.

• WACC employs partial screen update and asynchronous communication
• With WACC, asynchronous communication replaces synchronous request/response model
• WACC is not an application, but an Integrated Solution. Analysis is an initial phase, followed by re-programming of web application.
• WACC can be implemented on existing web applications without having to rewrite the entire application from scratch
• Built in a robust way, the data is available to user only till user session is available
• Security is a priority in WACC. Data is fetched only when a screen requests the same
• WACC helps cache data for subsequent requests
• Not only data but client side validation scripts can also be cached using WACC
• User can continue to use the application while the client application requests information from the server in the background. When new information arrives, only the related user interface portion is updated

• Reduces excessive server load and bandwidth consumption due to redundant page refreshes
• Applications become lot more interactive
• Prevents loss of operation context during page refresh
• It is not specific to a particular programming language, data exchange format, or network communications object
