I understand how a firewall might be configured to block Java or ActiveX 
executable files, by looking at the file extension. How does a firewall 
understand what is JavaScript or VBScript when that code is simply part 
of a comment in an HTML document? Does it now have to be an HTML 
interpreter as well?
