I was looking to fix my website display bugs on IE. As a result on the apple website, from internet explorer, we are directly redirected to Microsoft Edge, and I would like to know how to apply it to my own website. Anyone knows how to do that ?
Microsoft maintain a list of websites which should be redirected from IE to Edge. It isn't something you can configure yourself.
Consider using some kind of client-side detection (ideally feature detection for something you depend) and display an "Unsupported Browser" message with links to some suggested browsers instead.
