SPA

It is common nowadays to have the acronym for SPA as a Single Page Application.

Nevertheless the actual meaning is quite different, the page is not single, the page is actually shelled.

SPA approach has the same idea as in a mobile application or a thin desktop client. A user downloads a thin shell for the app: a header, a footer, a body placeholder and possibly sidebars. Then asynchronously this app updates the content for the placeholders, while footer and header is not reloaded.

From a user experience the app is working with several navigation links and many pages. So calling such shelled app layout as a one page sounds misleading.
