server_name for localhost actually matches <anything>.localhost

[oscaretu]

Hello, Gianluigi

I suppose the response is coming from the default server: if the vhost
servername of the request doesn't match any of the defined ones, the answer
will come from the default server. If you add an alternate servername
"test.localhost" where you defined "localhost" in the config file, you
should see the same content that you see when you  use "localhost"

Kind regards,
Oscar
