There is an open source project named Sitemesh.NET which uses the approach we have discussed in the previous section for applying a common theme for a web site. Sitemesh.NET is a web-page layout and web-application integration system which helps in creating large sites for which a consistent look/feel, navigation and layout scheme is required. It is a port of Sitemesh, a JSP implementation of the same idea using the GangOfFour Decorator design pattern. You can get more details on this project from their Sitemesh web site.
