SiteSpect's Cookies

SiteSpect requires three cookies for optimal operation:

  • SSID – SiteSpect User Tracking Cookie
  • SSRT – SiteSpect Recent Request Cookie, also includes information about robot testing
  • SSOD – Other Data Cookie

SiteSpect can operate with a small risk of data loss using only two cookies: User Tracking (SSID), and Combined Recent Request and Additional Data (SSRO) Cookies.

All other cookies are optional but without them some features may be limited.

  • Status Signaling Cookie (SSSC)
    • SiteSpect does not use this cookie for testing or user tracking. We set this cookie so you can log SiteSpect GUIDs, Visits, Campaigns, and Variation Group data. You can disable it without affecting any SiteSpect operations. However without it you will need WATTS to collect SiteSpect data in a third-party tool.
    • The following breaks down the data in this cookie: [Site ID].[GUID].[Visit Count]|[Test Camp. ID1].[Variation Group ID1]:[Test Camp. ID2].[Variation Group ID2]:[Test Camp. ID3].[Variation Group ID3]
  • Preview Cookie (SSPV)
    • SiteSpect uses this cookie only during preview sessions unless the logging level is set to the maximum debug detail. As long as the logging level is below debug, this cookie is set only for users in a preview session. Real traffic uses this cookie only if logging is set to debug.
  • Affinity Cookie (SSLB)
    • SiteSpect does not use this cookie for testing or user tracking. We set this cookie as a routing indication to the client's infrastructure. If the client is routing 100% of traffic to SiteSpect or using another affinity mechanism, you don't need this cookie. You can use this cookie Origin Experiment Campaigns, but it is not required.

Origin Experiments can use a cookie that is configured by the individual Variation (note that Origin Experiments can use headers instead).

OmniChannel and Ancillary Cookie are two features that capture data from our client's cookies but SiteSpect doesn't touch them.

The SSAAUTH, SSADUSR, and SSUSER cookies are used by the SiteSpect Interface.

SSRT Yes Recent request tracking Stores the date and time of the user's last request to determine if the visit has timed out. This cookie is typically updated every 60 seconds, but you can configure the frequency in the SiteSpect Interface.

In addition, it stores information about the robot test (does SiteSpect think this person is a robot, how many tries of the robot test have we done).
