Apache Web Server

Apache Web Server

Apache Web Server (usually just called Apache, Apache HTTP Server) is a fast, secure software package that runs more than half of all web servers around the globe. It's been the world's most popular web server since 1996, just one year after it was first released.

Apache is open-source (free) software distributed by the Apache Software Foundation, which promotes various other free and open-source advanced web technologies. Despite this, the Apache webserver provides a full range of features, including CGI, ​SSL, and virtual domains; it also supports plug-in modules for extensibility.
Although Apache was originally designed for Unix environments, more than 90 percent of installations run on Linux. It's also available for Windows and other operating systems.

What is HTTP Server?

A server, in general, is a remote computer that serves files to requesting clients. A web server, then, is the environment in which a website runs — the computer the serves the website.

A web server delivers content using the Hypertext Transfer Protocol (HTTP). For example, when you visit Lifewire.com in your web browser, you're ultimately contacting the web server that hosts this website so that you can communicate with it and request web pages (which you've already done to see this page).

Use Of Apache HTTP Server And Why We Use It?

One of the most significant benefits to Apache is that it's free for both personal and commercial uses, so you never have to worry about paying for it.

Despite that fact that it's free, Apache is a reliable software framework that is actively maintained. Frequent feature upgrades, security patches, and vulnerability improvements are ongoing.

Apache doesn't skimp on features, either. In fact, it's one of the most feature-filled HTTP web servers available, which is another reason it's so popular.

Apache Extensibility

Modules add more functions to the software. Apache supports:
  1. Password authentication and digital certificates
  2. Customizable error messages
  3. Virtual hosting capabilities
  4.  Proxy services
  5. SSL and TLS
  6. GZIP compression to speed up web pages

Apache Features

Here's a handful of Apache's other features:
  1. IPv6
  2. XML
  3. FTP
  4. Perl, Lua, and PHP
  5. Bandwidth throttling
  6. WebDAV
  7. Load balancing
  8. HTTP/2
  9. Htaccess
  10. Multiple Request Processing modes
  11. URL rewriting
  12. Session tracking
  13. Geolocation based on IP address

Learning how to use Apache is not nearly as difficult as its wealth of features suggests. It's so widely used that answers to virtually any question you could ask are readily available online in the many users' forums and websites. Checking these is a good idea for experienced users, too, because the software remains a regularly updated solution that continues to evolve along with the internet itself.

How Apache web server works?

In an idle state, the Apache server listens to various IP addresses that are being determined in its Config file. Whenever the requests are received, it quickly analyzes the headers and applies the protocols as specified in this file. This further helps take appropriate action, therefore making it a swift affair.

One web server can handle countless websites depending on its memory capacity and other crucial factors. To the outside world, it appears as if all the websites are independent, despite of the fact that all are going to eventually mapped to the same machine. The concept of virtual hosts comes into the picture where the sites are termed as virtually different.
“The method of hosting a wide range of domain names under the name of a single server or a pool of servers is what we call Virtual Hosting.”
The most famous examples of web hosting companies are – GoDaddy, HostGator, DreamHost, InMotion, Bluehost, 1&1, and A2 Web Hosting. Any firm, whether it is a start-up or an already established company, has a website and the domain is purchased online at one of the mentioned web hosting companies. The web hosting company has several packages at different prices. The buyers decide the best suitable ones, based on their current status of the business.
