w3ServerPool

w3ServerPool names the D3 server pool to which you wish to connect. The server pool can span several D3 servers. If w3ServerPool is not specified in the URL, the server pool named "default" is used. If the specified server pool does not exist, or if no free connections are available, an error message is returned to the browser.
