Dynamic http upstream based on Host-Header an DNS/LDAP lookup

[Marten Lehmann]

I tried to distinguish the proxy and the upstream module. Is the 
upstream module a raw tcp connection level module, that sends and 
returns packets to backends while the proxy module actually understands 
HTTP and is able to look for a host header and similar?

If that's right, then we definetely have to extend the proxy module for 
our use case.
