I am doing work for a client who forces compatibility mode on all intranet sites. I was wondering if there is a tag I can put into my HTML that forces compatibility mode off
As suggested in this answer to a related question, "edge" mode can be set in the Web.Config file. This will make it apply to all HTML returned from the application without the need to insert it into individual pages:
This same step can also be accomplished by modifying the "HTTP Response Headers" using IIS Manager for the IIS server, entire website, or specific applications.
