You want to use routes.
http://wiki.coldbox.org/wiki/URLMappings.cfm
Also, your second URL should have been
http://localhost/index.cfm/Global/about
not
http://localhost/index/Global/about
Using routes will allow you to use URLs such as
http://localhost/index.cfm/about
And if you want to get rid of the “index.cfm”, the link I provided shows you how to do that as well.
In that case, your URL could just be
http://localhost/about
Thanks!
