httpd::cookie - Cookie management
The package httpd::cookie provides a number of convenient commands for the setup and use of cookies.
See http://wp.netscape.com/newsref/std/cookie_spec.html for the specification of what cookies are and how they work.
Creates new cookie using the specified options and stores it internally. See section Cookie options for the allowed options and their meaning.
Takes all the cookies which were created in the specified interpreter (via Cookie_Set) and instructs the Http protocol engine (see package httpd) to return them to the browser. If no interpreter is specified the current interpreter is used as data source.
Low-level command to encode the specified options into a cookie. The generated cookie is not stored internally but returned as the result of the command. See section Cookie options for the allowed options and their meaning.
Looks in the environment created by the Http protocol engine (see package httpd) for cookies sent by the browser and return a list of cookie values which match the specified key (cookie).
Danger: This command prefers the data in the environment variables (HTTP_COOKIE) over the data in the request status array. This means that at certain points in the processing of a request the data returned by this command is out of sync with the actual data in the request status array. A concrete example of this are access control hooks (See Url_AccessUnInstall). When they are called the CGI environment has not yet been (re)initialized, meaning that this command will return the cookie data for the last request, and not of the current one.
