Forum OpenACS Q&A: detail nsunix/nsvhr again

yes, I run thre servers: master, ciao, www.ewayweb.net
The "ciao" and "www.ewayweb.net" configuration files are two that differs in name and port (8001 and 8080) only and they are configures as they work indipendently whithout any modification (no nsvhr module)
in ciao.tcl
httport=8080, hostname=ciao
in dev-ewayweb.tcl
httport=8001, hostname=www.ewayweb.net

 ns_section "ns/server/${server}/module/nssock" 
          ns_param   port         $httpport 
          ns_param   hostname     $hostname  
          ns_param   address      $address

The master.tcl file is:
