I have a SharePoint tenant where we are working to redirect some existing pages over to landing pages that are providing instructions for migrating. Needed something short and sweet to flip it over without much trouble. It’s easier to manage with a meta rather than fighting the “making your external client side javascript work with SharePoint” fight. This one takes less than 5 minutes.

So via SharePoint Designer:

<meta http-equiv="refresh" content="0;url=http://your-url-goes-here" />

That’s it. Onto the next one!
