As a Web developer, there are three main actions you need to know in order to work with cookies; in fact, you will probably only use the first two:
send— Send a cookie, or reset the value of an existing cookie
get— Get, or read, the value of an existing cookie
delete— Delete an expired cookie by setting its expiration date to the past. (This option is not often done and may not be handled as expected by the browser.)
Oracle provides a package, OWA_COOKIE, with procedures that allow you to perform each of these actions (Table 15.2). Other elements in the OWA_COOKIE package, such as the OWA_COOKIE type, provide additional built-in support for cookies.
