Analytics Cookies

Adobe Analytics uses cookies to differentiate requests from different browsers and to store helpful information that an application can use later. They may also be used to associate browsing information to customer records.
In particular, Analytics uses cookies to anonymously define new visitors, help analyze clickstream data, and track historical activity on the website, such as response to particular campaigns or the length of the sales cycle.
More information is available in Analytics help about First-Party Cookies .

Cookies Set By Plug-ins

Additional cookies can be set depending on the use of Analytics plug-ins. These cookies are snippets of code available to the client for use in a variety of circumstances. These circumstances include: retrieving values from the URL; concatenating values to pass to Analytics; capturing form abandonment, and so on. For specifics on cookies that are set by each plug-in, contact ClientCare. An example would be the s_vh cookie used with the Set Once Per and Set and Get Last Value plug-ins.
Conversion variables (eVarX) passed in on a image request without JavaScript, such as code placed within an email, are attributed properly only if the email client and web browser share the same cookie space.
