Yes, it's the referrer URL:

    inevow.IRequest(ctx).getHeader('Referer')

Note the incorrect spelling of the header name.

In my experience, it's not too common for the referrer header to be
disabled but it's certainly not something that can relied on completely.

The only way I know to reliably redirect back to where they came from is
to pass the initial page's URL through as a request parameter. Horrible,
I know.
