How It Works
When constructing and working with URLs in an application, it is sometimes benefi-
cial to extract information pertaining to an URL. This can be easily done using the
URL built-in class methods, which can call a given URL and return strings of informa-
tion.
Table 21-1
explains the accessor methods available in the URL class for obtaining
information.
