Before starting a dialogue with a web server through HTTP protocol, what connection must be established for the client?
With the web server through a UDP connection
With the default gateway through a UDP connection
With the default gateway through a ICMP connection
With the web server through a TCP connection
With the default gateway through a TCP connection
With the web server through a ICMP connection
HTTP data exchange depends on the TCP protocol, which guarantees reliable delivery and segments data requests and responses into smaller pieces. TCP is a connection-oriented protocol, which means that when a client starts a dialogue with a web server, the TCP will open a connection, over which the HTTP data will be transferred. When the dialogue is complete the connection should be closed.
