Methods and apparatus to determine main pages from network traffic

A non-transitory computer readable medium comprising instructions that, when executed, cause an audience measurement computing system to perform operations comprising:

• accessing, by one or more servers and via a first network interface of the one or more servers, main pages:
• collecting, by the one or more servers and via the first network interface, first network traffic data associated with the access to the main pages;
• based on the collected first network traffic data, identifying by the one or more servers, for each accessed main page, a pattern requested uniform resource identifiers (URIs) corresponding to response times of the requested URIs;
• generating, by the one or more servers, training data comprising the patterns;
• transmitting, by the one or more servers, the training data to a media device via the first network interface;
• collecting, by the media device via a second network interface of the media device, second network traffic data associated with access to at least one of the main pages;
• identifying, by th media device, a set of URIs from the second network traffic data;
• and
• detecting, by the media device, the at least one of the main pages based on a comparison of the set of URIs with the patterns of the training dat received from the one or more servers.

A method performed by an audience measurement computing system comprising one or more servers and a media device, the method comprising:

• accessing, by the one more servers and via a first network interface of the one or more servers, main pages:
• collecting, by the one or more servers and via the first network interface, first network traffic data associated with the access to the main pages;
• based on the collected first network traffic data, identifying, by the one or more servers, for each accessed main page, a pattern of requested uniform resource identifiers (URIs) corresponding to response times of the requested URIs:
