Slim and optimized C++ implementation (the executable file of the service is only 76Kb in size)
	Thoroughly tested multi-threaded implementation.
	Support for static and dynamic content through the writing and publishing of Server Extensions.
	Support in the Server Extensions for all HTTP methods: GET, POST etc.
	Smart caching mechanism for both dynamic and static content.
	I/O completion port based winsock server listening by default at the TCP port 49274.
	Customizable listening port: in the release available from this page the port is set to 48001 through the "port.inf" file.
	"MZ signature check" on all the returned content: no user can get by mistake a Server Extension (that actually is a Windows PE Module) suitable for reverse engineering attacks.

	Create a DLL module with Visual Studio.
	Include the file "WebServerCommon.h", whose source is included below in this same page.
	Define an exported function with this prototype and name: extern "C" __declspec(dllexport) size_t _cdecl ProcessHttpRequest( UINT uiProtocolVersion, SServerFunctions& ssf, BYTE* pbRequest, size_t sRequestLen, BYTE* pbResponse, size_t sResponseBufferLen, unsignedlong ulLocalAddr, unsignedlong ulRemoteAddr );
	Examine the request data available through the variables pbRequest/sRequestLen and write the HTTP response in the pbResponseBuffer, that is sResponseBufferLen bytes in size. Return the number of bytes written in the buffer as the return value of the export function itself.
	Compile, build and rename the dll with a ".dyn" extension.
	Copy the ".dyn" file in the wwwroot directory or in one of its subfolders in order to publish it through the WWW Server.
