Change "/login" url

Hi! I have configured a Reverse Proxy to handle ".../login" requests (and we can use pas.plugins.headers now) - however we want to be able to use the "legacy login" i.e. Plone's own login at the same time. We could use a second URL for that, like ".../login_old". How can I change the URL of the default Plone login / add an additional route for it, like ".../login_old"?

There are the /login_form and /failsafe_login (unstyled) variants

You can also register your own login view by re-using this config:

<!-- put this extra <configure> section somewhere in your configure.zcml -->
<configure package="Products.CMFPlone.login">
  <browser:page
      name="my_custom_login"
      for="plone.base.interfaces.INavigationRoot"
      class=".login.LoginForm"
      template="templates/login.pt"
      permission="zope.Public"
      />
</configure>

Note that the class and template attributes are based on Products.CMFPlone.login

OMG Plone is magnificent! Thank you so much, @petschki !!!
