From StockListDemo readme:
Edit the "index.html" and "popup.html" source files. They both call the
"lsPage.context.setDomain" method with a null argument. The argument should
be modified to specify the domain name of the machine that will be running
the Web Server (e.g. "").
I am testing it on my development computer. its full name is computername.domainname.local
How do I specify "" in this case?
