What Is a Web Server and How Does It Work?

Web Server Defined (Request to Response)

A web server is the program that accepts HTTP(S) requests from browsers and returns the pages, images and data they ask for — the software layer your website actually lives on.

Key points:

• It listens on port 80 (HTTP) and 443 (HTTPS), serving responses with status codes like 200 or 404.

• The big four: Apache, Nginx, LiteSpeed and IIS (Windows).

• Static files stream straight from disk; dynamic pages call PHP-FPM or application runtimes first.

• Virtual hosts let one machine serve many sites on one IP.

• Server choice shapes WordPress speed — LiteSpeed with LSCache out-serves default stacks.

On shared hosting the provider runs this layer for you — see shared hosting — while what a CDN adds covers the edge layer in front of it.

Static vs Dynamic Content and PHP-FPM

How this plays out with Apache: settings that look cosmetic usually decide page speed and uptime under real traffic. The defaults WebJi® ships are tuned for Indian network conditions, and support can review your setup on request.

Ports, Virtual Hosts and Many Sites per Server

Allow 80 and 443 to the world, and restrict SSH (22) or RDP (3389) to known IPs. A site that times out after a firewall change is usually a closed web port, not a dead server. If you lock yourself out, use the console in the client area or email support@webji.services before you reboot in a loop.

Why Your Host's Web Server Choice Matters

On IIS, the honest summary is that defaults matter more than brand names — a well-set budget plan outranks a mis-tuned premium one. WebJi® documents its defaults openly and adjusts them per ticket when workloads need it.
