Parameter is null by default. No value is given. Code says it is not null.

I replaced all == with "is" for path and domain. Here are results:

Name: A 1  Expires null: true  Path equals null: true  Domain 
null: true
Name: A 2  Expires null: true  Path equals null: false  Domain 
null: false
Name: A 3  Expires null: true  Path equals null: false  Domain 
null: false
Name: A 4  Expires null: true  Path equals null: false  Domain 
null: false
Name: A 5  Expires null: true  Path equals null: false  Domain 
null: false
~~~~~~~~~
Name: A 6  Expires null: true  Path equals null: false  Domain 
null: false
Name: A 7  Expires null: true  Path equals null: false  Domain 
null: false
Name: A 8  Expires null: true  Path equals null: false  Domain 
null: false
Name: A 9  Expires null: true  Path equals null: false  Domain 
null: false
~~~~~~~~~
Name: A10  Expires null: true  Path equals null: false  Domain 
null: false
Name: A11  Expires null: true  Path equals null: false  Domain 
null: false
Name: A12  Expires null: true  Path equals null: false  Domain 
null: false
Name: A13  Expires null: true  Path equals null: false  Domain 
null: false


Could you try the code yourself as well? Because something is 
clearly wrong here. I even have removed "shared" from everywhere, 
results are still as above. There is no way "Expires" becomes 
null, and "Path" and "Domain" become false.
