Nowadays, most web-centric applications are developed using Python, Java, C#, PHP, and other high-level languages. But, for these applications, people place reverse proxies, such as NGINX, Apache Web server, or IIS redirector, to manage the traffic . All of these reverse proxies are written in C++. Likewise, most of the web browsers and HTTP client libraries, such as libwww
, libcurl
, and WinInet
, are written using C++.
One reason why Java, (statically-typed) C#, and other dynamic languages (such as Python, Ruby, and PHP) became popular is the fact that these languages support reflective capabilities (in the case of static languages, such as C#/Java) and duck typing (supported by dynamic languages). These features help web application servers to load web page handlers dynamically. Read about them by searching for keywords such as Reflection API and Duck Typing.
