A downside of this single-threaded approach is that Node.js does not allow vertical scaling by increasing the number of CPU cores of the machine it is running on without using an additional module, such as cluster, [55] StrongLoop Process Manager, [56] or pm2. [57] However, developers can increase the default number of threads in the libuv ...

Subsequent requests by the client are permissible. 405 Method Not Allowed A request method is not supported for the requested resource; for example, a GET request on a form that requires data to be presented via POST ...
Express.js, or simply Express, is a back end web application framework for building RESTful APIs with Node.js, released as free and open-source software under the MIT License. It is designed for building web applications and APIs. [2] It has been called the de facto standard server framework for Node.js. [3]
FastCGI, SCGI, and AJP which allow long-running application processes handling more than one request to be hosted externally; i.e., separately from the Web server. Each application process listens on a socket; the Web server handles an HTTP request and sends it via another protocol (FastCGI, SCGI or AJP) to the socket only for dynamic content ...
For a typical web application, the application server sits behind the web servers. An application server framework is a service layer model. It includes software components available to a software developer through an application programming interface. An application server may have features such as clustering, fail-over, and load-balancing.
The mod_proxy_ajp module performs a similar function to this module, while being integrated into the mod_proxy framework. mod_lbmethod_bybusyness: Version 2.3 and newer: Stable Extension: Apache Software Foundation: Apache License, Version 2.0: Pending Request Counting load balancer scheduler algorithm for mod_proxy_balancer.

The Spring Framework is an application framework and inversion of control container for the Java platform. [2] The framework's core features can be used by any Java application, but there are extensions for building web applications on top of the Java EE (Enterprise Edition) platform.
A Jakarta Servlet, formerly Java Servlet is a Java software component that extends the capabilities of a server. Although servlets can respond to many types of requests, they most commonly implement web containers for hosting web applications on web servers and thus qualify as a server-side servlet web API .
