I have a requirement to develop common pages with web parts and all authoring capabilities that should be hosted in the top level site and can be shared among all sub sites. The advantage of this should be as long as the sub sites don't want to customize
this common page for look and feel or authorizing content this page will be served as a common page and yields the performance benefits.
But when the sub site wants to customize the common page, it will have its own copy and any changes made to the common page shouldn't be available for the customized common page.
How can I achieve this?
I tried with the application page by hosting them into the 14\TEMPLATE|Layouts folder, but couldn't see the publishing capabilities enabled.
Help will be greatly appreciated.
