What you needed is the referrer. http://stackoverflow.com/questions/1471188/how-do-i-get-the-referrer-url-in-an-asp-net-mvc-action

>That's what I do presently Craig, but how do I know where the action was invoked ? e.g. The action can be invoked from my "Index" view of all Employees or a view showing a list of employees linked to a department, if the latter is true I want to return to the "list of employees linked to a department" not the "Index" view. This is me still on my learning curve of Web stuff so there's no urgency, thanks for your time.
