Why Do Chrome\'s Session Cookies Persist After Browser Closure on Mac OS X Lion?
Why Do Chrome\'s Session Cookies Persist After Browser Closure on Mac OS X Lion?
Chrome Browser's Perplexing Session Cookie Preservation
In an attempt to store session cookies using JavaScript, users have encountered an unexpected discrepancy in Chrome's cookie handling. Despite setting an expiration time for these cookies, they persist even after closing the browser and restarting it.
Investigating Chrome's Cookie Behavior
Further investigation revealed that this peculiar behavior is limited to Chrome on Mac OS X Lion, while other browsers and operating systems delete session cookies as expected. This anomaly prompted users to delve deeper into Chrome's session management settings.
The Revelation: "Continue Where You Left Off"
It was discovered that the "Continue where you left off" option, when enabled in Chrome, leads to the retention of session cookies. This option keeps tabs and sessions active even after closing the browser, overriding the session cookie expiration rules.
Chrome's Inconsistent Cookie Behavior
The question then arises: why does Chrome behave differently on Mac OS X Lion compared to other operating systems? The answer to this remains elusive, but users are speculating that it may be related to Lion's implementation of the session resumption feature.

Getting Started With Chart.js: Pie, Doughnut, and Bubble Charts
Mar 15, 2025 am 09:19 AM
This tutorial will explain how to create pie, ring, and bubble charts using Chart.js. Previously, we have learned four chart types of Chart.js: line chart and bar chart (tutorial 2), as well as radar chart and polar region chart (tutorial 3). Create pie and ring charts Pie charts and ring charts are ideal for showing the proportions of a whole that is divided into different parts. For example, a pie chart can be used to show the percentage of male lions, female lions and young lions in a safari, or the percentage of votes that different candidates receive in the election. Pie charts are only suitable for comparing single parameters or datasets. It should be noted that the pie chart cannot draw entities with zero value because the angle of the fan in the pie chart depends on the numerical size of the data point. This means any entity with zero proportion
