Cookies are used for a number of different purposes, ranging from authentication information, to user preferences, to more nefarious things such as user-tracking with personalised, unique user identifiers. This could be either up to a certain date of expiration (standard cookies) or only temporarily until you close your browser (session cookies). Cookies are one way how websites can store data on your machine. Cookie : This header field contains a list of name-value pairs (name1=value1 name2=value2).There are lots of different content types and sub-types: text/plain, text/html, image/jpeg, application/json. Accept: This is a list of MIME types, which the client will accept as response from the server.This is exactly what we will do with our scrapers - make our scrapers look like a regular web browser. Because these headers are sent by the clients, they can be modified ( “Header Spoofing”). This header is important because it is either used for statistics (how many users visit my website on mobile vs desktop) or to prevent violations by bots. In this case, it is my web browser (Chrome) on macOS.
