I've enabled the "Publish Server Side Includes" labs feature. I've defined my editable regions in the user control. The region is editable and I'm able to go in and make my changes. I can publish these changes and they show up within pagelime on the page. However once viewed in another tab, the changes do not show nor has the file actually been edited on the server when I check it via FTP.
Is this feature actually working correctly with ASCX pages? Is there something I'm missing here? Seems pretty straightforward but the publish is not actually editing the usercontrol file.
