COOKIES & TYPES ?

1. How often we blame it on cookies for tracking,invading our privacy.......but whats these cookies all about?How many types exist?Are all of them dangerous?What can I do to avoid them? All answers ahead in my posts ahead....

2. A cookie, also known as an HTTP cookie, web cookie, or browser cookie, is used for an origin website to send state information to a user's browser and for the browser to return the state information to the origin site.The state information can be used for authentication, identification of a user session, user's preferences, shopping cart contents,or anything else that can be accomplished through storing text data.Cookies are not software.They cannot be programmed, cannot carry viruses, and cannot install malware on the host computer .

SESSION COOKIE

A session cookie only lasts for the duration of users using the website. A web browser normally deletes session cookies when it quits. A session cookie is created when no Expires directive is provided when the cookie is created.

PERSISTENT COOKIE

A persistent cookie will outlast user sessions. If a persistent cookie has its Max-Age set to 1 year, then, within the year, the initial value set in that cookie would be sent back to the server every time the user visited the server. This could be used to record a vital piece of information such as how the user initially came to this website. For this reason, persistent cookies are also called tracking cookies or in-memory cookies.

SECURE COOKIE

A secure cookie is only used when a browser is visiting a server via HTTPS, ensuring that the cookie is always encrypted when transmitting from client to server. This makes the cookie less likely to be exposed to cookie theft via
eavesdropping.

HTTP ONLY COOKIE

The Http Only session cookie is supported by most modern browsers.On a supported browser, an Http Only session cookie will be used only when transmitting HTTP (or HTTPS) requests, thus restricting access from other, non-HTTP APIs (such as JavaScript). 

FIRST PARTY COOKIES 

A first-party cookie either originates on or is sent to the Web site you are currently viewing. These cookies are commonly used to store information, such as your preferences when visiting that site.

THIRD PARTY COOKIES

Third-party cookies are cookies being set with different domains than the one shown on the address bar.For example: Suppose a user visits www.example1.com, which sets a cookie with the domain ad.foxytracking.com. When the user later visits www.example2.com, another cookie is set with the domain ad.foxytracking.com. Eventually, both of these cookies will be sent to the advertiser when loading their ads or visiting their website. The advertiser can then use these cookies to build up a browsing history of the user across all the websites this advertiser has footprints on.

ZOMBIE COOKIE

A zombie cookie is any cookie that is automatically recreated after a user has deleted it. 

TEMPORARY / SESSION COOKIES

A temporary or session cookie is stored only for your current browsing session, and is deleted from your computer when you close your browser.

UNSATISFACTORY COOKIES

Unsatisfactory cookies are cookies that might allow access to personally identifiable information that could be used for a secondary purpose without your consent.
