Do concurrent connections to an HTTPS website perform separate SSL handshakes?

Summary

– Concurrent connections to An HTTPS website do not require multiple SSL handshakes.
– instead, the SSL connection is reused for subsequent requests from the same client IP address and port number.
– this reuse of SSL connections is made possible By the Use of Session Identifiers in the TCP/IP stack.

the SSL/TLS Protocol is responsible for securing communication between a client and a server over the internet. when a client establishes An HTTPS connection with a server, It must first Perform An SSL handshake to authenticate the server and negotiate a shared secret key for encryption. the resulting encrypted SSL connection is then used to Exchange Data between the two parties.

However, Once An SSL connection has been established, subsequent requests from the same client do not require another SSL handshake. instead, the existing SSL connection is reused as long as the client IP address and port number remain the same. this reuse of SSL connections is made possible By the Use of Session Identifiers in the TCP/IP stack.

when a client sends An HTTP request over An encrypted SSL connection to a server, the server returns a response containing a Session identifier. the client then uses this Session identifier for subsequent requests to the same server, allowing the server to reuse the existing SSL connection rather than requiring another handshake. this reuse of SSL connections can significantly improve the performance and efficiency of HTTPS communication.

in some cases, a client may initiate multiple Concurrent connections to An HTTPS website. for example, a web browser might open multiple tabs for different pages on the same site, each Using its own SSL connection. However, even in this case, the SSL handshake Only needs to be performed Once per IP address and port number combination. subsequent requests from the same client over existing SSL connections will reuse the Session Identifiers and the previously established Encryption key rather than performing another SSL handshake.

in Summary, Concurrent connections to An HTTPS website do not require multiple SSL handshakes. instead, the SSL connection is reused for subsequent requests from the same client IP address and port number. this reuse of SSL connections is made possible By the Use of Session Identifiers in the TCP/IP stack, which allow Servers to maintain encrypted communication with clients without requiring repeated SSL handshakes.
