ev_sync_variable name Cookie

Element Description

Purpose

Media Optimizer sets the ev_sync_variable name cookie to record the date when synchronization will be performed. This is an ad exchange-specific cookie that synchronizes the Media Optimizer user ID with the partner's ad exchange platform. It is created for new users and sends a synchronization request when it expires. The ev_sync_variable name cookie contains the synchronization date in yyyymmdd format and is set in the eversttech.net domain.

The variable name in the cookie indicates that this description and behavior applies to all Media Optimizer cookies that start with ev_sync_. These cookies can appear with a variety of terms appended to the end of the name. Some common examples include, but are not limited to, the following:

  • ev_sync_ax
  • ev_sync_bk
  • ev_sync_dd

Media Optimizer cookies that start with ev_sync_ are ID synchronization cookies.

Expiration Time

31-days (default), but you can change this in the configuration file for the ad exchange.
