Which open-source web server holds 70 percent of the market share?

The Apache HTTP server is recognized for commanding a significant share of the web server market, often cited around 70 percent. This dominance is attributed to several factors, including its robust features, flexibility, and extensive support for various programming languages and modules.

Apache is an open-source platform, which means it can be freely modified and distributed, fostering a large community of developers who contribute to its improvement and security. It supports a wide range of operating systems, making it versatile for deployment in different environments. Furthermore, its reliability and performance capabilities have led it to be the server of choice for many developers and businesses.

In contrast to the other options, Microsoft IIS and ASP.net are proprietary technologies, which limits their widespread adoption compared to open-source solutions like Apache. Netscape, once a prominent player in web technology, has largely faded in relevance and is no longer a significant competitor in the modern web server landscape. Hence, Apache HTTP server stands out as the leading choice among web servers, reflecting its substantial market presence.
