Url Aliases "Assign some nice, user- and seo-friendly URLs (like /company/about) to not so nice ones (like /node/13) - and, well, have an ability to access sub-urls in a nice way, too (like /company/about/edit in the example above). An additional behaviour is to redirect the user to a 'nice' url (/company/about) when he accesses the original one (/node/13)"
script_name "The initial portion of the request URL's "path" that corresponds to the application object, so that the application knows its virtual "location". This may be an empty string, if the application corresponds to the "root" of the server."
