I noticed there're 2 types of "s_vi" cookies.
[1] regular one
Name: s_vi
Value: [CS]v1|HEX-HEX[CE]
Domain: COMPANIES_NAME.122(or121).2o7.net
[2] another one
Name: s_vi_RANDOMIZED VALUE
Value: [CS]v4|HEX-HEX|RANDOMIZED VALUE[CE]
Domain: 2o7.net
What's the difference between [1] and [2]?
And, what kind of situation [2] is created on?
Thanks in advance for your help.
