Web History (PRIM_WEB.History)
Browser History object
Ancestors - Object (PRIM_OBJT)
History provides access to the browser history. Manipulation of the browser history is limited to the currently active domain and is effectively a place to store QueryStrings that will be appended to the URL. This is primarily useful for storing deeplinking information generated by user navigation.
In this example, every time an item in a list gets focus the details of an employee are displayed and an item is added to the history. When the user uses the history to show a page, the URLChanged event can be monitored and the URLParameters processed to detect the employee number.
