redirect question

Question

In a C# 2010 web application that I need to make changes to, there is code that says Page.Response.Redirect("test.aspx"). What does that mean versus Response.Redirect("test.aspx").

Is the part called "page' part of the command? The aspx pages I am using are also in a folder called 'page'.

Thus can you tell me what the 'page' is referring to in the statemnet above?
