// rel -- Coresponds with the BLOC software release (e.g., 2.5, 2.6, etc) that the user intends on launching.  The default is "2.5".

// ver -- Which "version" of the selected release should be launched? (e.g., experimental / dev, alpha, beta, GA)  The default is "GA".

// loc -- Which datacenter "location" should be contacted for this user's desired BLOC? (e.g., sales, server.iad, UK, BANA)  The default is "server.iad"

// override -- Normally the BLOC will not be launched if the user's PC is not qualified.  By setting this to "1", testing can be performed ahead of opening up support for additional PC configs.  Default is "0" (no / false)

// autolaunch -- Should the jnlp be launched automatically once the user's PC is certified as "supported".  Default is "1" (yes / true).

// debug -- This can be used to make the user's PC configuration available directly via the page.  The results are displayed at the bottom of the page.  This is particularly useful with autolaunch=0.  Default is "0" (no / false).
