Managing cookie data

A method for providing a cookie to a user, the method comprising:

• assigning, by the one or more processors, a user identification to a user;
• identifying, by the one or more processors, a consolidated set of internet activities by the user, wherein the internet activities are identified by the user identification;
• analyzing, by the one or more processors, data in the consolidated set of internet activities by the user, wherein said data comprises a description of interactions with a website by the user from multiple client devices, wherein said analyzing is triggered by tags, within webpage code for the website, being sent to a current client device currently in use by the user, and wherein executing the tags results in an application program interface (API) call to an analytics component that captures a click stream of internet activities by the user using the multiple client devices;
• generating, by the one or more processors, a server side cookie for the website based on the analyzed data, wherein the server side cookie is an analytics cookie that provides a real-time analysis of the internet activities by the user using the multiple client devices, wherein the analytic s cookie is periodically updated to describe a rate of internet accesses by the user, and wherein the server side cookie is generated in a cloud of computing resources;
• in response to the user visiting the website with a first client device, transmitting, by the one or more processors, the server side cookie from the cloud of computing resources to the first client device;
• initiating a merging, by the one or more processors, of the server side cookie with a client side cookie at the first client device to create a merged cookie, wherein the client side cookie includes a session-based tracking cookie that monitors browsing activity of the user during a browsing of the website and an authentication cookie that authorizes the user to access the website while using the first client device, and wherein the merged cookie is a compact cookie that is smaller than a sum of the server side cookie plus the client side cookie;
• determining, by the one or more processors, that the merging of the server side cookie with the client side cookie at the first client device takes less than a predefined length of time, wherein a timer starts at a beginning of the merging in order to determine how long the merging is taking;
• in response to determining that the merging of the server side cookie with the client side cookie at the first client device takes less than the predefined length of time, completing the merging of the server side cookie with the client side cookie and using the merged cookie in the first client device.
