How do I get the current absolute URL in Ruby on Rails?

Question

How can I get the current absolute URL in my Ruby on Rails view?

The request.request_uri only returns the relative URL

None of the suggestions here in the thread helped me sadly, except the one where someone said he used the debugger to find what he looked for.

I've created some custom error pages instead of the standard 404 and 500, but request.url ended in /404 instead of the expected /non-existing-mumbo-jumbo.

What I needed to use was

request.original_url
