Cookie 信息
Cookie It is actually a short piece of text information (in key-value format). The client initiates a request to the server, and if the server needs to record the user status, a Cookie is issued to the client browser using response. The client browser will save the Cookie. When the browser requests the site again, the browser submits the request along with the Cookie to the server. In general, Cookie is the carrier of information, which can help us to better maintain our website, to ensure that you can have a good use environment.
Cookie Multiple types. They work in roughly the same way, but there will still be subtle differences. The following Cookie is the Cookie we need to use when running the website:
a.Session Cookie
This type of cookie is only valid during the session, which closing the browser. The way to set session cookie is not to set Expires before creating cookie.
b.Persistent Cookie
Persistent cookie, as the name suggests, works in user sessions for a long time. When you set the cookie attribute Max-Age to 1 month, then each related URL http request contains this cookie in this month. So it can record a lot of user initialization or customization information, such as when the first login and weak login state. c.Secure cookie
c.Secure cookie
The secure cookie is a cookie form under https access to ensure that the cookie is always encrypted while passing from the client to the Server. This greatly reduces the probability of cookie content being directly exposed to hackers and stolen.
d.HttpOnly Cookie
Major browsers already support httponly cookie.1.IE5+ 2.Firefox 1.0+ 3.Opera 8.0+ 4.Safari/Chrome。On a httponly-enabled browser, the cookie set to httponly can only be passed on http (https) requests. That is, httponly cookie is invalid for the client script language (JavaScript), thus avoiding JS stealing cookie during a cross-station attack. When you use javascript to set the cookie with the same name, only the original httponly value is transmitted to the server.
e.3rd-party cookie
The first party cookie is cookie planted under the domain or subdomain of the browser address bar. Third-party cookie is planted under a different domain name from the browser address bar. For example, when users visit a.com, they have a cookie in ad.google.com, and a cookie in ad.google.com, when they visit b.com. This scene often occurs in google adsense, Ali Mama. Advertisers can collect some user habits and access history.
f.Super Cookie
Super cookie is the set of the cookie on the public domain name prefix. Usually the cookie of a.b.com can be set in a.b.com and b.com while not allowed to be set in. On com, but unfortunately, some older versions of browsers have produced super cookie because of insufficient filtering of new suffixes.
