Understanding how FreeWebs works [CLOSED]

[goofy180173]

I found out by reading in the forum that freewebs only listens to the url and not to the IP. So If I want to host more than on Webapp I have to add a virtual network and bridge it to my physical. Then I have to add this to a DNS and add a new webapp to Freewebs.
If I want to make this Webapp available from the internet I also have to give an extra IP and add this to the external DNS.
Or is there an other way to make this Webapp available by using my main-url with a different port and redirect it with the router to the IP of the secound Webapp.
I think it´s not possible, but maybe.

You did not have to create a virtual IP
FreeWebs works with virtual hosts.
Your clients need to resolve the web server name associated to the server ip, that all

how do I do this?
I added the first app (z-push) to the url <host>.<mydomain>.at and it works.
I added the second app (webApp) to the url webapp.<mydomain>.at
The secound Webapp displays a yellow triangle and I don´t know how to access to it. If I type the url, the page could not be found.
If I type the IP z-push answers.
The Resolv column of the webapp is also not checked.
Is it enough to add the webapp.<mydomain>.at to /etc/hosts to the same IP than mail.<maydomain>.at?

yep

you should have on your C:\Windows\system32\drivers\etc\host these entries
10.10.10.2 webapp.<mydomain>.at
10.10.10.2 webapp1.<mydomain>.org
10.10.10.2 webapp2.<mydomain>.it
10.10.10.2 webapp3.<mydomain>.com
