Internet Explorer Cookie Internals (FAQ). Grr... IE 6, 7 and 8 don’t support the max-age cookie argument, forcing you to use an explicit expiry date instead. This appears to affect the cache busting cookie pattern, where you set a cookie to expire in 30 seconds for any user who posts content and use the presence of that cookie to skip caches and/or send their queries to a master instead of slave database. If you have to use expires, users with incorrect system clocks may get inconsistent results. Anyone know of a workaround?
