What are the cookies in mobile phone UC?

Cookies, when used in programming, are a technology that allows the website server to store a small amount of data in the client's hard disk or memory, or read data from the client's hard disk. When you browse a website, a very small text file placed on your hard disk by the network server can record your user ID, password, pages you visited, stay time and other information. When you come to the website again, the website can read Cookies and get your relevant information, so you can take corresponding actions, such as displaying a welcome slogan on the page, or allowing you to log in directly without entering an ID or password. It can be regarded as your ID card in essence. But Cookies cannot be executed as code, nor can they spread viruses, and they are exclusive to you and can only be read by the server that provides them. The saved pieces of information are paired with Name/Value (Name-Value).

Pairs), the "name/value" pair is just a named data.

A website can only get the information it puts on your computer, it can't get the information from other Cookies, and it can't get anything else on your computer.

Most of the contents in Cookies are encrypted, so the average user seems to be just meaningless alphanumeric combinations, and only the CGI processor of the server knows their true meaning.
