IE 11 will not work offline

Using HTML5, I have created an application that is accessible offline.  If I open IE 11 while on line and access the application (caching needed files) and then disconnect my machine from the network, everything works perfectly.  Once I close IE when offline and try to access the site again, I get a web page that states I am currently not on a network.  I have checked my manifest file, mime types on IIS, checked for issues with IE developer tools and still nothing.

How do I get IE to load the cached pages?
