Configuring outputcache of Ghosted Page Layouts


We have many page layouts which are deployed in the "12" folder of MOSS and are Ghosted into the BD by MOSS.

We are going through the step of configuring the cache on the site collection and we want to set specific Cache Profiles to certain Page Layouts.

If we do it via the Master Page Gallery, the Page Layouts are "unghosted" and therefore disconnected from the copy on disk.  We cannot deploy them with WSP and we receive this error when trying to open a page again :

The attribute 'autoeventwireup' is not allowed on this page.

OutputCache with SqlDependency


I'm new to the asp.net forum, so Hello!

After doing some research, I arrived at the conclution that the best caching method for my needs is the built in OutputCache of asp.net. I saw that this directive includes a SqlDependency option and that has a CommandNotification option. Looking in to that, I found only talk of SQL Server 2005.

Has this option been deprecated?

Is there a better option?

What I'm looking to do is cache a page as long as the underlying data has not been changed. I'm using SQL Server 2008 R2 as the backend to the site.
