Why should a .nocache.js file never be cached?

1.	Why should a .nocache.js file never be cached?
Answer» GWT compiler generates .nocache.js file every time with the same name whenever a GWT application is compiled. So browser should always download the .nocache.js file to get the latest gwt application. gwt.js code actually appends a unique timestamp at the end of the file name so that browser always treat it a new file and should never cache it.
