I have a community setup and recently added a custom url to move from the
sitea.force.com url schema to our own domain of ourdomain.org.
For instance, I added the new custom domain of
siteb.ourdomain.org and the community is accessible at that address. I want to redirect all users coming in to
sitea.force.com to the new URL at
siteb.ourdomain.org. How can I do this? The site redirect rules won't quite do this. Any ideas?
