Interface to Remove Cookies
CgiCC HTTPCookies supports MaxAge that may be 0 (browser) or positive
according to RFC,
Other very important options Expires is not supported. This option is mostly
useless because requires
definition of absolute time. However one special case exists: Cookies
Removal.
In many cases it is very useful to remove cookies by setting Expiration date
in past.
I've written a little patch to fix this problem, please consider to merge it
into upstream
