[Klug-general] Indentifing Local machines on website

[Mike Evans]

 From memory this will be to do with the Java sandbox.  It means that 
you can only access files from the URL that the webpage came from.  So 
maybe one option is to distribute your page to each of the terminals so 
that it loads from there and could then access a local file which would 
be different in each case.

A more sophisticated way would presumably be to tinker with the security 
policy of the JVM to allow access to the resource you want.
