什么是Cookie?
A cookie, also known as an HTTP cookie, web cookie, or browser cookie, is a small piece of data sent from a website and stored in a user’s web browser while a user is browsing a website. When the user browses the same website in the future, the data stored in the cookie can be retrieved by the website to notify the website of the user’s previous activity. Cookies were designed to be a reliable mechanism for websites to remember the state of the website or activity the user had taken in the past. This can include clicking particular buttons, logging in, or a record of which pages were visited by the user even months or years ago.
(上面的解释来时wikipedia)
在Windows系统上(这里以Win7为例)浏览器的Cookie
IE浏览器Cookie数据位于:%APPDATA%\Microsoft\Windows\Cookies\ 目录中的xxx.txt文件 (里面可能有很多个.txt Cookie文件)
如:C:\Users\yren9\AppData\Roaming\Microsoft\Windows\Cookies\0WQ6YROK.txt
在IE浏览器中,IE将各个站点的Cookie分别保存为一个XXX.txt这样的纯文本文件(文件个数可能很多,但文件大小都较小);而Firefox和Chrome是将所有的Cookie都保存在一个文件中(文件大小较大),该文件的格式为SQLite3数据库格式的文件。
Firefox的Cookie数据位于:%APPDATA%\Mozilla\Firefox\Profiles\ 目录中的xxx.default目录,名为cookies.sqlite的文件。
如:C:\Users\jay\AppData\Roaming\Mozilla\Firefox\Profiles\ji4grfex.default\cookies.sqlite
在Firefox中查看cookie, 可以选择”工具 > 选项 >” “隐私 > 显示cookie”。
Chrome的Cookie数据位于:%LOCALAPPDATA%\Google\Chrome\User Data\Default\ 目录中,名为Cookies的文件。
如:C:\Users\jay\AppData\Local\Google\Chrome\User Data\Default\Cookies
在Linux系统上(以Ubuntu 12.04 和 RHEL6.x 为例)浏览器的Cookie
Firefox的Cookie路径为:$HOME/.mozilla/firefox/xxxx.default/目录下的cookie.sqlite文件。
