What is the best approach and status code for temporary maintenance pages?

What would be the best practice approach and most desirable HTTP status code for website / application pages that should not be displayed temporarily?

Describe possible alternatives -

  • Leave the user in the current URL, but return a different status code and the contents of the “service”? Maybe 503 codes? SO question - The correct status code for redirecting the maintenance page
  • Redirect from URL to a specific service page - code 302 or 307?
  • Add temporary routing i.e. mod_rewrite, direct request to the temporary maintenance page?

Also, with regard to caching and expiration, would it be better to set the header to the no-cache date or past expiration date if there is an expected time line in the maintenance window?

The first option is almost certainly the best. It seems the most appropriate title seems Retry-after.
