Hi ruben0909,
Previously with version 3.5 you could connect via the web through web access. Is this possible in version 4?
Yes it is still possible 🙂
You can also use Web Companion to connect to a server 4 with a client 3.
Furthermore, Portal Server (product of the new version 4) offers a javascript client meaning nothing needs to be installed on the client side at all. Users simply connect via any browser.
