A user device may receive a request for content; provide the request to a first server; receive an instruction based on providing the request for content; and provide a message to a second server based on receiving the instruction. The message may cause the second server to embed a unique identifier (ID) of the user device in the message to form a modified message for transmission to a third server. The modified message may cause the third server to form an object having the unique ID. The user device may receive the object based on providing the message to the second server; provide the object to the first server or to a fourth server; and receive, from the first server or the fourth server, particular content based on providing the object to the first server or the fourth server. The particular content may be based on the unique ID.
