Apache::Request cookie handling methods?

[princepawn]

p.209 of the Eagle Book states that Apache::Request has some
experimental cookie-handling functions. However, neither perldoc
Apache or perldoc Apache::Request has the word cookie anywhere in
their body.

CGI::cookie() is wonderful, but I feel funny using CGI.pm and
CGI::Cookie under mod_perl and would much rather use Apache API
methods.  

Could someone point me to the documentation for apache-based cookie
handling?
