Is there a creative approach to identifying a distinct user using JavaScript, such as generating a hash to transmit to the server-side?
EDIT: The challenge is that I am unable to access the browser directly (e.g. set cookies). Additionally, relying on IPs is not feasible. The solution must be implemented on the client-side using JavaScript.
One way to tackle this issue is by generating a distinct identifier on the server side and then sending it to the browser as a cookie (after verifying if the cookie already exists for the current browser).
Various advertising networks frequently employ this method to collect demographic data about internet users.
UPDATE Additionally, the "unique ID" could simply refer to the initial session ID linked to the user, which can often be provided by several frameworks.
While I did upvote Brian's response, I feel it is important to mention the challenge of identifying a distinct user. Requesting this to be accomplished solely in Javascript can be problematic as it is stateless beyond the page level unless there is involvement at the server level. This approach may not yield successful results.
An example of a "distinct" identifier could be the MAC address of the user's device, but keep in mind that this could pose privacy concerns as well.
The server already has access to the user's IP address, so there is no need to gather this information using JavaScript.
