[C++][DOWNLOAD] Simple Webserver

[Jakash3]

Even though I haven't provided a formal release of this library yet, I am offering you a download of a web server made from the AXCEL C++ Library that includes all the source code.

The compiled windows binary is there and the source can also be compiled on GNU/Linux. When compiling, keep in mind that there is usually a lot of .cpp file dependencies to compile your main file with, they are located in the src folder.

Download: http://www.mediafire.com/?li1f6vk6yl64ahj
Example usage:

Code:

server C:/Users/Bob 9000

Recommended but not necessary to have index.html in every folder and 404.html in the root folder.

server.cpp

Code:

#include "axcel/inc/Socket.h"
#include "axcel/inc/Thread.h"
#include "axcel/inc/Mutex.h"
#include "axcel/inc/String.h"

#include "axcel/inc/console.h"
#include "mimes.cpp"
