Preferred way to include relative reference to JavaScript in VS 2008 nested Masterpage

Question

Our base Masterpage has something like the following

Answer 1

As per ScottGu,

One tip to take advantage of is the relative path fix-up support provided by the head runat="server" control. You can use this within Master Pages to easily reference a .CSS stylesheet that is re-used across the entire project (regardless of whether the project is root referenced or a sub-application):

The path fix-up feature of the head control will then take the relative .CSS stylesheet path and correctly output the absolute path to the stylesheet at runtime regardless of whether it is a root referenced web-site or part of a sub-application.
