Cookies in our surveys

When you fill in a survey your browser makes many requests to our system - to submit your answers, to fetch pages of questions, and to fetch associated images, video and styling.

Cookies are necessary to maintain your session during this process, so we can remember the answers you've given until you get to the end of the survey, and route you appropriately through the survey.

The cookies listed below are used to facilitate this, and are deleted at the end of your session. Please note that if you're filling in a survey within a panel or community site that we host then the cookies used to maintain your session there are also used for the survey (this may also mean a site specific session cookie such as 'eDR_eGP_PanelSite' may be present instead of PHPSESSID).
