Not only are browsers free to ignore more than X cookies they are also allowed to purge anything more than Y bytes in the cookies from any given domain. [nb] You really should read the original Netscape Cookie spec -- it's short and clear and concise, and possibly one of the best-written specs out there, in some ways. [/nb] So I would never recommend serializing a bunch of data to get it all into one cookie. imho. Better to give the browser ONE cookie and use that to track everything else on the server in a session. This also matters for bandwidth -- It would do Google no good at all to trim down their homepage to the Nth degree like they do, if they sent an extra 100K of coookie data back and forth all the time. Remember: Whatever you SEND in the Cookie, the browser has to send BACK on every page hit, every image hit, the CSS, the javascript requests, all of them, to the same domain. Serialized data is seldom "small" so even a handful of datastructures being sent back by the browser on every request could add up quickly. The user has to wait for that data to get to your server, after all, before they can even BEGIN to get your content back. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
