Apache’s extensive feature set makes it a versatile and powerful web server choice for a wide range of applications and scenarios.
How Apache Web Server Works
Apache, as a web server, relies on the TCP/IP protocol for communication over networks. In the realm of web communication, it primarily utilizes the HTTP/S protocol. By configuring specific IP addresses and ports in its configuration files, Apache listens for incoming requests from clients. The Listen directive enables Apache to accept and route traffic to designated ports and domains, allowing for effective management of web communication.
When a message successfully reaches its intended destination through Apache, an ACK (Acknowledgment) message is sent back to acknowledge the successful delivery. This confirmation ensures reliable and efficient communication between the server and the client.
However, in the event of data transmission errors, Apache sends a NAK (Negative Acknowledgment) message to request the retransmission of the lost or corrupted data. This proactive approach ensures the integrity and accuracy of the exchanged information, guaranteeing smooth and uninterrupted communication between the server and the client.
