Instance Method Details

#forwarded_hosts ⇒ Object

Parses the forwarded host header and returns an array of forwarded hosts

For example:

If the HTTP_X_FORWARDED_HOST header was set to 
  'some-domain.com, some-other-domain.com, and-another-domain.com'

This method would return [‘some-domain.com’, ‘some-other-domain.com’, ‘and-another-domain.com’]

Returns an empty array if there aren’t any forwarded hosts

def forwarded_hosts
  hosts = env['HTTP_X_FORWARDED_HOST'].to_s.split(/,\s*/)
  unless hosts.empty? || hosts.first != hosts.last
    hosts << env['HTTP_HOST'] unless env['HTTP_HOST'].blank?
    env['HTTP_X_FORWARDED_HOST'] = hosts.join(', ')
  end
  hosts
end

#forwarded_uris ⇒ Object

Parses the forwarded uri header and returns an array of forwarded uris

For example:

If the HTTP_X_FORWARDED_URI header was set to 
  '/some/path, /some/other/path, /and/another/path'

This method would return [‘/some/path, ’/some/other/path’, ‘/and/another/path’]

Returns an empty array if there aren’t any forwarded uris
