If you would be so kind as to post the code that you are using to read the cookies then perhaps someone could help.

It is not possible to have two cookies with the same name and same path stored in one browser.

It is possible for one user to log in from two different browsers or machines giving the appearance of two cookies, or you might have a case (or errant character) problem with foo, or you might have two foos with different paths (not even sure this is possible but in theory it should be).

However, without some code to look at I suspect most folks will just be guessing.
