Today, I was working with dokku, and I found myself in need of a wildcard subdomain. A wildcard DNS record is a record that will match requests for non-existent subdomains. For instance, if you set a wildcard DNS record to
*.example.com, and a user requests
foo.example.com, etc.. the requests will be forwarded to whichever server
*.example.com points to.
