Web servers usually use a well-known TCP port 80. If the port is not specified in a URL, browsers will use this port when sending HTTP request. For example, you will get the same result when requesting and .
При симметричном шифровании обмен данными происходит по отдельности и тому же ключу, который знают сервер как и клиент.
Because each transaction on the HTTP protocol is carried out independently of the others and without reference to the history, the connection between the web browser and the server ends after the transaction is finished. This makes HTTP a stateless protocol.
HTTPS has been shown to be vulnerable to a range of traffic analysis attacks. Traffic analysis attacks are a type of side-channel attack that relies on variations in the timing and size of traffic in order to infer properties about the encrypted traffic itself. Traffic analysis is possible because SSL/TLS encryption changes the contents of traffic, but has minimal impact on the size and timing of traffic.
Set up a reverse proxy cache: A proxy server like Varnish can cache HTTPS responses and serve those before requests hit backends.

However, this is done over a secure SSL connection. The SSL connection is responsible for the encryption and decryption of the data that is being exchanged to ensure data safety.

HTTP is not encrypted and thus is vulnerable to man-in-the-middle and eavesdropping attacks, which can let attackers gain access to website accounts and sensitive information, and modify webpages to inject malware or advertisements.

With HTTP, the requests from client to server and responses from server to client are in plaintext. This https://gradeproject.eu/ means the traffic can be read by any parties that intercept it along the way.
Naturally, a third party cannot guarantee against the undetected theft or unauthorized use of a certificate. However, procedures are in place to revoke certificates that are stolen or misused, and they expire, forcing servers to periodically obtain new ones.
