Test live and from different countries the HTTP responses, redirect chains and status codes of one or multiple URLs.
This translates to extra load on server resources for HTTPS compared to HTTP. The impact is more pronounced on underpowered servers or those handling high volumes of requests.
It is the SSL certificate that distinguishes the two web protocols. Actually, HTTPS is an HTTP protocol that has been made more secure.
HTTP operates at the highest layer of the TCP/IP model—the application layer; as does the TLS security protocol (operating as a lower sublayer of the same layer), which encrypts an HTTP message prior to transmission and decrypts a message upon arrival.

Understanding the trade-offs between HTTP vs HTTPS allows developers and users to make informed decisions about when to use which protocol. The sections below go over the key differences, pros and cons, and performance impacts in detail.
Однако таким сертификатам не доверяет большинство браузеров, а потому в основном ими пользуются в локальных или корпоративных сетях.
Индивидуальный сертификат выдается только одному ресурсу.
HTTPS is a secure version of the original Hypertext Transfer Protocol (HTTP) that prevents eavesdropping and other types of attacks that can breach personal privacy https://gradeproject.eu/ and erode data integrity.
The plaintext nature of HTTP allows intermediate servers and CDNs to efficiently cache and serve frequently accessed static content. The encrypted HTTPS data cannot be cached in the same way.

HTTPS uses a well-known TCP port 443. If the port is not specified in a URL, browsers will use this port when sending HTTPS request. For example, you will get the same result when requesting and .
Other key differences between SSL and TLS that make TLS a more secure and efficient protocol are message authentication, key material generation and supported cipher suites, with TLS supporting newer and more secure algorithms.
