I am running 4 separate Productcart  catalogs. The problems I have is the catalogs are sharing cookies happens because I am using all sites in the same domain name (all the folders are different). Two solutions I have read about is to create them as separate sites in IIS and use a sub domain instead of folder path. Examples are  http://mystore.mydomain.com/" rel="nofollow - mystore.mydomain.com    vs.   www.mydomain/mystore. This is easy to do except I use EV SSL certificates for the domain I have now. It is not a willdcard ssl so I would need to purchase 4 new certificates which will have a cost. The other option would be cheaper, but I don`t know how to configure is put all catalog sites in their own application folders, and each application folder to use it's own application pool.

Try adding the following line and unique variable to the StoreConstants file for each store:

private const scID=1

You can insert this line immediately after the 'StoreURL' variable, and just make sure that each store has a unique variable. So the 2nd store would use the following:

private const scID=2

... and so on.

This should prevent sessions from 'crossing over' from one store to another. If you have additional questions on this, please submit a support ticket for security reasons.

can you be more specific? I tried as you mention and I get a server error. Here is my storeconstants file, please indicate where I would place the code. I changed all the private info for security reasons. 

Thanks,

You can add it right after the line for  'StoreURL'. E.G.:

%>

I tried as you described and put the code exactly where you said. When I reload the file I get the error 

Do I need to make any changes to my webserver??

Thanks,

Gary
