//	a META refresh tag, it will need the absolute address (determined by a Session
//	variable prepened to the path).  However, if the PDF document is loaded right away into
//	the window by the function below, a relative address is needed and created by prepending
//  a ".." to the root relative path. 
//
//	If the "bOpenQuickly" flag is set to TRUE, then a javascript function will determine
//	if the window is open and can receive the PDF file.  This is quick, but on some browsers, the
//  DownloadPDFFileInProgress window fails to fully load before it begins opening the PDF file.
//
//  If the "bOpenQuickly" flag is set to FALSE, the window will be opened normally
//	and the PDF document will be loaded into it when the DownloadPDFFileInProgress page 
//  refreshes from a dynamically generated META tag.
