Great!! Thanks Jamie... it was only one of my last two days problem 😊
Now...
first: for master I don't installed openacs (I think it's rigth(?))
second: I configured ciao, www.ewayweb.net and master in my client's /etc/hosts to same address (192.168.198.7)
Then master:8001, ciao:8080 and www.ewayweb.net:80 each one serve me its home page.
I thougth that
if I request ciao:8001 then I'd have the same page of ciao:8080
so
if I request www.ewayweb.net:8001 then I'd have the same page of www.ewayweb.net:80
In fact I have the page master:8001
What's wrong.
tahnks.
