HTTP request

Created: 2022-09-23

HTTP request helps user send instructions to web-server such as:

• getting informations
• updating informations
• deleting informations

The following are the instructions that we send to the server:

• A URL identifying the target server and resource (e.g. an HTML file).
• A method that defines the required action.

Web servers wait for

1. client request messages,
2. process them when they arrive,
3. reply to the web browser with an HTTP Response Status Codes.

Additional information can be encoded with the request (for example, HTML form data). Information can be encoded as:

• Client-side cookies. Cookies contain session data about the client, including keys that the server can use to determine their login status and permissions/accesses to resources.
