Why is my asp:Substitution control suddenly not working in ASP.NET 4.0?
- by Steve Wortham
I just upgraded my site from ASP.NET 3.5 to 4.0. I've been working through some breaking changes and there were more than I expected.
One I can't figure out, however, is why my <asp:Substitution /> control suddenly stopped working like it should. It's supposed to ignore the output cache settings of the parent page and update upon every request. For some reason that isn't happening. It's caching for the full 10 minutes (the OutputCache setting for my home page). Any ideas?
