SAS applications are
displayed with the Flex interface that is provided by a particular
version of SAS Application Themes for Flex. At start-up time, Flex
applications load Flex themes automatically. A theme consists of SWF
files that include cascading style sheets (CSS) files. The theme content
is downloaded to the client, and is cached by the user's Web browser.
As a result, during subsequent uses of the Web application, the theme
content loads quicker than when it is initially loaded. The SAS Corporate
theme is the default theme for SAS applications that use Flex themes.
