How HTTP request passes through OSI layers for communicating the web server?

In this way, HTTP is the top layer in a "protocol stack" of "HTTP over TCP over IP," as depicted in Figure shown below. A secure variant, HTTPS, inserts a cryptographic encryption layer (called TLS or SSL) between HTTP and TCP .

HTTP Request Vs ISO layers
When HTTP wants to transmit a message, it streams the contents of the message data, in order, through an open TCP connection. TCP takes the stream of data, chops up the data stream into chunks called segments, and transports the segments across the Internet inside envelopes called IP packets . This is all handled by the TCP/IP software; the HTTP programmer sees none of it.
