PHP application server

LWAS is a web server with SSL and HTTP/1.1 support, designed to serve applications using either SocketPairs or popen as inter-process communication mechanisms.

This architecture allows LWAS to integrate applications written in multiple programming languages, both compiled and interpreted, including but not limited to C, C++, Pascal, Go, Rust, PHP, and Python.

LWAS supports two execution and communication models:

SocketPairs provide full-duplex, bidirectional communication between the server and application workers. This model is intended for persistent workers, high-performance scenarios, and advanced use cases where fine-grained control over communication, buffering, and custom protocols is required. It is well suited for compiled languages and long-lived processes.

popen offers a simpler execution model based on standard input/output streams. This approach prioritizes ease of use and portability, making it suitable for scripting languages and straightforward request–response execution, typically with one process per request.

The currently available examples are implemented using PHP and the popen model for simplicity. As LWAS continues to evolve, additional examples using other languages and communication models will be provided.
