I have been asked by our Infrastructure unit whether the webinator version we currently run (Webinator 5.1.46-Windows-w/plugin) will run on a Virtual Server environment?
One consideration is that only one version of the underlying Texis software can run on a single machine. So all virtual servers on a single machine that would use Webinator need to use the same version.
And another consideration is the scripts location. If you use the INSTALLDIR/texis/scripts location all virtual servers will be using the same set of scripts. If you use the %DOCUMENT_ROOT% location each will use it's own scripts. In the latter case make sure you configure the directory where you place the scripts to not allow downloads.
I guess there may be some confusion about what "virtual server" means.
If you mean a virtual machine where there are multiple operating systems (or multiple copies of one) running in isolation from each other on a single computer (VMware, MS Virtual Server, Xen, etc) then there are no considerations. Webinator/Texis will work on any virtual machine just as it would on a dedicated machine.
If you mean a single operating system running an http server that serves many different domains, sites, or IPs then the considerations I mentioned above apply because Texis/Webinator will running on the same OS for all of those sites.
