What are cookies?

Cookies are small files that are created in system memory of the client or browser client (if temporary). It is used to address the state which I have already discussed in my article ViewState. We can store small pieces of information in a client system and use it when needed. The most interesting thing is that it works with the user clearly. It can easily be used everywhere in your web application. Cookies store information in plain text format.

 If a web application uses cookies, the server sends cookies and store client browser. The browser then returns the cookie to the server the next time the page is requested. The most common examples of using a cookie to be stored user information, user preferences, remember password option, etc. Cookies have many advantages and disadvantages. I will come to this later, but first, I'll take a look at how the cookies are started.
