I just discovered that performing an <esi:include src="url" />
using a network-path reference is not possible; it returns an error in the inclusion.
Is possible to include an absolute URL omitting the protocol/scheme?
I need to include pages via http or https depending on the protocol/scheme of the calling page
(so include http://example.com/included if I'm including in http://example.com/container, or include https://example.com/included if I'm including in https://example.com/container)
