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](http://www.mycompany.com) and they are [www.3rdpartycompany.com](http://www.3rdpartycompany.com). If the user  
pressed back and tries to login again the cookie is still stuck for  
[www.3rdpartycompany.com](http://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](http://3rdpartycompany.com) will not be sent to [mycompany.com](http://mycompany.com).  
Unless you mean something like [3rdpartysubdomain.mycompany.com](http://3rdpartysubdomain.mycompany.com) which a  
cookie that is set for the [mycompany.com](http://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](http://www.mycompany.com) which sends you to  
[www.billingcompany.com](http://www.billingcompany.com). At the [www.billingcompany.com](http://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](http://www.mycompany.com) to delete the  
cookies for [www.billingcompany.com](http://www.billingcompany.com)… I know they are not available  
when my browser is set to [www.mycompany.com](http://www.mycompany.com) but they are available  
when [www.billingcompany.com](http://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.
