HTTP
Also known as: HyperText Transfer Protocol
HyperText Transfer Protocol (HTTP) is an Internet protocol used when visiting websites. This protocol determines how visitors(browsers) and Web servers communicate with each other on the World Wide Web.
How does http work?
Within the protocol, a visitor sends a request (request) to a web server. The request is sent via the server's IP address. Thanks to the DNS system, this address does not need to be known to the user and websites can be identified by domain names. The request includes the address that the visitor wants to request. Technical information about the user is also sent along with any cookies. The server then sends a response to the user's browser consisting of the desired page or file.
What is the difference between HTTP and HTTPS?
Although HTTP and HTTPS have many similarities, the main difference is in data security. HTTP sends information in plain text, which means that the data being exchanged can be intercepted relatively easily by third parties, such as in a man-in-the-middle attack. HTTPS, on the other hand, uses a security certificate, such as SSL (Secure Sockets Layer) or TLS (Transport Layer Security), to encrypt the data. This means the information cannot simply be read by others, even if it is intercepted.
In addition, HTTPS not only provides better protection of sensitive data, such as passwords and payment information, but also increases user confidence. Many modern browsers display a lock icon in the address bar when a Web site uses HTTPS, while providing warnings for Web sites without a secure connection.
