A method to monitor media access by a mobile device, the method comprising: obtaining, from a panelist during a panelist registration process, by executing an instruction with a processor of a registrar, registration data including (i) panelist demographic information identifying a demographic of the panelist and (ii) a model of the mobile device associated with the panelist; assigning, in response to obtaining the registration data, by executing an instruction with the processor of the registrar, a port of a proxy to the mobile device; the port uniquely assigned to the mobile device; generating, in response to assigning the port to the mobile device, by executing an instruction with the processor of the registrar, a configuration file based on the model of the mobile device and comprising the port; transmitting, in response to generating the configuration file, by executing an instruction with the processor of the registrar, the configuration file to the mobile device, the configuration file instructing the mobile device to transmit future requests for media to the port; identifying, in response to receipt of a first request for media, by executing an instruction with a processor of the proxy, the panelist based on the port at which the first request is received, the first request originating from the mobile device; storing, in response to receipt of the first request, by executing an instruction with the processor of the proxy, first data indicative of the first request, the first request including monitoring data indicating the panelist having the demographic requested the media; requesting, by executing an instruction with the processor of the proxy, with a second request, the media from an Internet content provider identified in the first request, the Internet content provider being different than the proxy; storing, in response to receipt of the media, by executing an instruction with the processor of the proxy, second data identifying the media; storing, by executing an instruction with the processor of the proxy, an association of the panelist and the media; and transmitting, by executing an instruction with the processor of the proxy, the media to the mobile device. obtaining, from a panelist during a panelist registration process, by executing an instruction with a processor of a registrar, registration data including (i) panelist demographic information identifying a demographic of the panelist and (ii) a model of the mobile device associated with the panelist; assigning, in response to obtaining the registration data, by executing an instruction with the processor of the registrar, a port of a proxy to the mobile device; the port uniquely assigned to the mobile device; generating, in response to assigning the port to the mobile device, by executing an instruction with the processor of the registrar, a configuration file based on the model of the mobile device and comprising the port; transmitting, in response to generating the configuration file, by executing an instruction with the processor of the registrar, the configuration file to the mobile device, the configuration file instructing the mobile device to transmit future requests for media to the port; identifying, in response to receipt of a first request for media, by executing an instruction with a processor of the proxy, the panelist based on the port at which the first request is received, the first request originating from the mobile device; storing, in response to receipt of the first request, by executing an instruction with the processor of the proxy, first data indicative of the first request, the first request including monitoring data indicating the panelist having the demographic requested the media; requesting, by executing an instruction with the processor of the proxy, with a second request, the media from an Internet content provider identified in the first request, the Internet content provider being different than the proxy; storing, in response to receipt of the media, by executing an instruction with the processor of the proxy, second data identifying the media; storing, by executing an instruction with the processor of the proxy, an association of the panelist and the media; and transmitting, by executing an instruction with the processor of the proxy, the media to the mobile device.
