Forum OpenACS Q&A: Response to Development branch hosed?
ForceHostP will issue a redirect to the "cannonical hostname"
If the hostname parameter of nssock does not translate to
something the client can resolve the redirect will fail. It uses
[ns_conn location] to determine the url to which to redirect.
If you are going to use an IP for Address you will also need to
provide an IP or hostname for nssock's hostname parameter
(and 0.0.0.0 for hostname would probably be a bad choice unless you
are only ever going to connect from localhost).
