Res Redirect

Redirects to the URL derived from the specified path, with specified status, a positive integer that corresponds to an HTTP status code . If not specified, status defaults to "302 "Found".

res.redirect('/foo/bar')
res.redirect('http://example.com')
res.redirect(301, 'http://example.com')
res.redirect('../login')

Redirects can be a fully-qualified URL for redirecting to a different site:

res.redirect('http://google.com')

Redirects can be relative to the root of the host name. For example, if the application is on http://example.com/admin/post/new, the following would redirect to the URL http://example.com/admin:

res.redirect('/admin')

Redirects can be relative to the current URL. For example, from http://example.com/blog/admin/ (notice the trailing slash), the following would redirect to the URL http://example.com/blog/admin/post/new.

res.redirect('post/new')

Redirecting to post/new from http://example.com/blog/admin (no trailing slash), will redirect to http://example.com/blog/post/new.

If you found the above behavior confusing, think of path segments as directories (with trailing slashes) and files, it will start to make sense.

Path-relative redirects are also possible. If you were on http://example.com/admin/post/new, the following would redirect to http://example.com/admin/post:

res.redirect('..')

A back redirection redirects the request back to the referer, defaulting to / when the referer is missing.

res.redirect('back')
