If many backend sites share the same ip, and you refer all of them
with the same name (or ip) in proxy_pass directive, you probably
want to use somethine like

proxy_set_header Host <name>;

to make sure backend will be able to distinguish them. Or just

proxy_set_header Host $host;

to pass what you've got from client.
