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
Makefile
simpleServer.c
Configuration File
simpleServer.conf
DocumentRoot "."
Listen 8888
ThreadLimit 4
AddHandler copyHandler
This file is an AppWeb configuration file.
It is configured to run single-threaded and assumes that
the sample is being run from the current directory.
You should modify the DocumentRoot and Listen directives
to suit your application's needs.
Makefile
The Makefile will build on Windows or Linux. A Windows VS 6.0 project
file is also supplied.
Typical output from the Makefile build is listed below. This is the
output on a Windows system:
cl -o simpleServer.exe simpleServer.c -Zi -Od -D_NDEBUG -W3 -nologo -MDd -FD -DWIN -D_DLL -D_MT \
-D_WINDOWS -DWIN32 -D_WIN32_WINNT=0x500 -D_X86_=1 -D_CRT_SECURE_NO_DEPRECATE -D_USRDLL \
-I../../../include ../../../bin/libappwebStatic.lib ws2_32.lib advapi32.lib user32.lib
