DSP and DMP Cookie Mapping

DSP ad.com ads on the meijiu.com. Suppose DMP is called cm.api.taobao.com.

Create a GID mapping table

(1) ad.com is deployed on Meiju.com's page, pointing to DMP-----cm.api.taobao.com

(2) Then the user opens the Meijiu.com page of the browser and requests the-cm.api.taobao.com

(3) cm.api.taobao.com will 302 redirect to ad.com and attach the relevant GID information to the DSP for use. and returns a bacon (1*1 pixel picture)

The principle of 302 works is to upload the redirect address to the user's browser, and then the user's browser accesses the redirect's Destination address.

Using the GID mapping table

Check the table directly,

If not, then create a mapping
