Is it possible to provide version information to go with an HTTP cookie? I have a cookie which tells the page whether or not to prompt a user for action, based on whether or not the user wants the prompt. On a version upgrade of the page, I need to prompt the user regardless. Can I integrate this into my existing cookie?
A cookie is little more than a string with an expiry time. You can encode whatever information you like into that cookie, including a number representing a version.
