[Zope] how to prevent URL access to an external method?

[Pedro LaWrench]

What would you change on the security tab?  I still want my authenticated users to have access to the method as a call to it is made from unrestricted space (such as a page template), I just don't want them to call the method directly.

Why? It is more transparent and better way - use security tab.
