推荐答案

官方的最大大小为4KB，但我会preFER保持它的以及下的是：不超过几百个字节，顶部。

The "official" maximum size is 4KB, but I would prefer to keep it well under that: no more than a few hundred bytes, tops.

原因是，cookie是从客户端发送到服务器的每一个请求的 - 即使请求图像，CSS和JS文件时（如果它们驻留在同一台主机的something~~V应避免在一般，但对于小网站可能不值得麻烦）。这意味着，你会被要求在客户端传输4KB的为的每一个请求 - 记忆也是大多数消费者宽带已经上传速度比下载速度慢得多

The reason is that cookies are transmitted from the client to the server with every single request - even when requesting images, css and js files (if they reside on the same host something you should avoid in general, but for small sites may not be worth the bother). That means that you'll be requiring the client to transmit 4KB for every request - remembering also that most consumer broadband has much slower upload speed than download speed.
