w3VM

w3VM names the D3 virtual machine to which you wish to connect. If w3VMis not specified in the URL, the first virtual machine on the specified host in the w3Agent.conf file is used. If there is only one virtual machine on a specific host, w3VM is not needed. w3VM is ignored on all FlashCONNECT versions 2.0 and later.
