Method and server for monitoring users during their browsing within a communications network

A monitoring server containing:

• a set of monitoring elements, and at least one implementing processor, configured to:
• receive a monitoring element request from a browser, wherein the monitoring element request is cookieless;
• determine whether the request is a first request from the browser by comparing the set of monitoring elements to the monitor element request for similar monitoring elements;
• calculate an identifier for the browser comprising a counter and a browser fingerprint when the request is the first request such that the set of monitoring elements is not similar to the monitor element request, then determine a cache duration value associated with each monitoring element of the set, wherein the cache duration value is determined using a counter, and transmit the set of the monitoring elements and the values to the browser;
• and
• determine the identifier for the browser based on the monitoring elements requested in the request when the request is not the first request such that the set of monitoring elements includes a similar monitoring element to the monitor element request.

A server comprising:

• a monitoring server containing a set of monitoring elements, and at least one implementing processor, configured to:
• receive a monitoring element request from a browser, wherein the monitoring element request includes at least one monitoring element, wherein the monitoring element request is cookieless,
• determine whether the request is a first request from the browser, wherein the determination comprises identifying a match between the at least one monitoring element of the monitoring element request and the set of monitoring elements of the monitoring server,
• calculate an identifier for the browser comprising a counter and a browser fingerprint in response to the determination that the monitoring element request is the first request, then determine a cache duration value associated with each monitoring element of the set wherein the cache duration value is determined using a counter, and transmit the set of the monitoring elements and the values to the browser,
• determine the identifier for the browser based on the monitoring elements requested in the request in response to the determination that the monitoring element request is not the first request, and
• a content server.
