Why is My Session Data Disappearing Only in Chrome, and How Can I Fix It?

Session Data Vanishes Exclusively in Chrome: Resolving a Puzzling Anomaly

Just like the issue described in the linked thread, web developers have encountered a perplexing behavior with session data loss solely in Google Chrome. Despite implementing the recommended solutions, the problem persists for some.

In this specific case, session data stored through $_SESSION is being lost in Chrome while remaining intact in other browsers like Firefox. Upon investigating the network activity, it was observed that the session cookie is being transmitted, suggesting that session initiation is not the underlying issue.

However, an astute observation revealed a 404 error being triggered in Chrome due to the absence of a favicon.ico file. This 404 error inexplicably caused a footer script to alter the session variables, resulting in data loss.

Therefore, the solution to this particular problem lies in rectifying the 404 error by providing a favicon.ico file. By addressing this seemingly innocuous issue, the session data integrity can be restored, preventing its unexpected disappearance exclusive to Chrome.
