Cookie crazy

We have a site that does not really use any cookies. However, after
login a cookie is set by a 3rd party company. Therefore, we are
www.mycompany.com and they are www.3rdpartycompany.com. If the user
pressed back and tries to login again the cookie is still stuck for
www.3rdpartycompany.com and they fail. Is there a way to use
cookies.delete or something like that to get rid of cookies from a
site that is not ours? We do not want to read the value just delete
it.

Cookies from 3rdpartycompany.com will not be sent to mycompany.com. Unless you mean something like 3rdpartysubdomain.mycompany.com which a cookie that is set for the mycompany.com domain. Either you're misinterpreting the situation or describing it incompletely/inaccurately here on the list.

What happens is this...you login and are sent to a 3rd party billing
company. Therefore, you login at www.mycompany.com which sends you to
www.billingcompany.com. At the www.billingcompany.com site they set a
cookie...unfortunately, people keep pressing the back arrow.... and
then they go forward and of course the cookie is already there and
flips out there system.

I would like to say everytime you hit www.mycompany.com to delete the
cookies for www.billingcompany.com.... I know they are not available
when my browser is set to www.mycompany.com but they are available
when www.billingcompany.com is open....so I want to clear them. Any
ideas? This is not an easy one...I know that and it may not even be
possible.
