An example method to monitor media exposure involves receiving a first request from a client device at an intermediary serving a first sub-domain of a first internet domain, the first request to be indicative of access to media at the client device; transmitting, from the intermediary, first data associated with the first request to a data collection server of an audience measurement entity and second data about the first request to an entity of the first internet domain; and in response to determining that the first request does not include a user identifier associated with the first internet domain, sending a first response from the intermediary to the client device, the first response to instruct the client device to send a second request to a second intermediary associated with a second sub-domain of a second internet domain, the second request indicative of the access to the media at the client device. ## Claims ### Claim 1 A method to monitor media exposure, the method comprising: receiving a first request from a client device at an intermediary serving a first sub-domain of a first internet domain, the first request to be indicative of access to media at the client device; transmitting, from the intermediary, first data associated with the first request to a data collection server of an audience measurement entity and second data about the first request to an entity of the first internet domain; and in response to determining that the first request does not include a user identifier associated with the first internet domain, sending a first response from the intermediary to the client device, the first response to instruct the client device to send a second request to a second intermediary associated with a second sub-domain of a second internet domain, the second request indicative of the access to the media at the client device. ### Claim 2 (depends on 1) The method as defined in claim 1, wherein the user identifier is a cookie. ### Claim 3 (depends on 1) The method as defined in claim 1, further including transmitting, from the second intermediary, third data associated with the second request to the data collection server of the audience measurement entity and fourth data associated with the second request to an entity of the second internet domain. ### Claim 4 (depends on 3) The method as defined in claim 3, wherein the third data includes a status of a second user identifier associated with the entity of the second internet domain. ### Claim 5 (depends on 3) The method as defined in claim 3, wherein the fourth data includes an identifier corresponding to the media, and a second user identifier associated with the second internet domain. ### Claim 6 (depends on 5) The method as defined in claim 5, wherein the identifier is a campaign identifier to identify an advertisement in the media. ### Claim 7 (depends on 5) The method as defined in claim 5, wherein the identifier is encrypted to prevent the entity of the second internet domain from recognizing the identifier. ### Claim 8 A system to monitor media exposure, the system comprising: an intermediary to: receive a first request from a client device at an intermediary serving a first sub-domain of a first internet domain, the first request to be indicative of access to media at the client device; transmit, from the intermediary, first data associated with the first request to a data collection server of an audience measurement entity and second data about the first request to an entity of the first internet domain; and in response to determining that the first request does not include a user identifier associated with the first internet domain, send a first response from the intermediary to the client device, the first response to instruct the client device to send a second request to a second intermediary associated with a second sub-domain of a second internet domain, the second request indicative of the access to the media at the client device. ### Claim 9 (depends on 8) The system as defined in claim 8, wherein the user identifier is a cookie. ### Claim 10 (depends on 8) The system as defined in claim 8, wherein the second intermediary is to transmit third data associated with the second request to the data collection server of the audience measurement entity and fourth data associated with the second request to an entity of the second internet domain. ### Claim 11 (depends on 10) The system as defined in claim 10, wherein the third data includes a status of a second user identifier associated with the entity of the second internet domain. ### Claim 12 (depends on 10) The system as defined in claim 10, wherein the fourth data includes an identifier corresponding to the media, and a second user identifier associated with the second internet domain. ### Claim 13 (depends on 12) The system as defined in claim 12, wherein the identifier is a campaign identifier to identify an advertisement in the media. ### Claim 14 (depends on 12) The system as defined in claim 12, wherein the identifier is encrypted to prevent the entity of the second internet domain from recognizing the identifier. ### Claim 15 A tangible computer readable storage disc or storage device comprising instructions that, when executed, cause a processor to at least: receive a first request from a client device at an intermediary serving a first sub-domain of a first internet domain, the first request to be indicative of access to media at the client device; transmit, from the intermediary, first data associated with the first request to a data collection server of an audience measurement entity and second data about the first request to an entity of the first internet domain; and in response to determining that the first request does not include a user identifier associated with the first internet domain, send a first response from the intermediary to the client device, the first response to instruct the client device to send a second request to a second intermediary associated with a second sub-domain of a second internet domain, the second request indicative of the access to the media at the client device. ### Claim 16 (depends on 15) The tangible computer readable storage disc or storage device as defined in claim 15, wherein the user identifier is a cookie. ### Claim 17 (depends on 15) The tangible computer readable storage disc or storage device as defined in claim 15, where the instructions, when executed, cause the processor to transmit, from the second intermediary, third data associated with the second request to the data collection server of the audience measurement entity and fourth data associated with the second request to an entity of the second internet domain. ### Claim 18 (depends on 17) The tangible computer readable storage disc or storage device as defined in claim 17, wherein the third data includes a status of a second user identifier associated with the entity of the second internet domain. ### Claim 19 (depends on 17) The tangible computer readable storage disc or storage device as defined in claim 17, wherein the fourth data includes an identifier corresponding to the media, and a second user identifier associated with the second internet domain. ### Claim 20 (depends on 19) The tangible computer readable storage disc or storage device as defined in claim 19, wherein the identifier is a campaign identifier to identify an advertisement in the media. ### Claim 21 (depends on 19) The tangible computer readable storage disc or storage device as defined in claim 19, wherein the identifier is encrypted to prevent the entity of the second internet domain from recognizing the identifier.
