w3Debug is a FlashCONNECT application debugging tool. If w3Debug is set, then the incoming CGI and form variables and outgoing Web page are written to the w3logs,Dump file. 0 = don't write the items, non-zero = write the items.
The value for this flag can be set in any of these ways:
Within the application: w3Debug = 1
Within the w3Apps Option attribute: add the letter "D"
Within the URL: ...&w3Debug=1...
Within the form: <INPUT TYPE=HIDDEN NAME=w3Debug VALUE=1>
