Simple Server Sample in C++

The simple HTTP server sample demonstrates how to add HTTP server functionality to your C++ application.

The sample is a multithreaded main program that listens on port 8888 for HTTP requests. By changing the value of the ThreadLimit directive in the configuration file to zero you can run single-threaded.

See also the equivalent C simpleServer sample.

Files

simpleServer.conf
simpleServer.cpp

Configuration File

simpleServer.conf

DocumentRoot "."
Listen 8888
ThreadLimit 4

LoadModule ejs ../../../lib/libejsModule
LoadModule egi ../../../lib/libegiHandler
LoadModule esp ../../../lib/libespHandler
LoadModule static ../../../lib/libcopyHandler

AddHandler egiHandler .egi
AddHandler espHandler ESP
AddHandler copyHandler 

This configuration file loads the embedded JavaScript module and the embedded server pages and embedded gateway interface, and static content handlers. It is configured to run with 4 pool threads. It assumes that the sample is being run from the samples C/simpleServer directory and so the module paths are relative to the lib directory in the samples source tree. Modify these module paths to suit your installation.

You should modify the DocumentRoot and Listen directives to suit your application's needs.
