* Important: HttpServer.dll was changed to HttpServer_OpenSim.dll so that the HttpServer references do not conflict if you've copied the OpenMetaverse.Http.dll and requirements to the OpenSimulator bin folder. This means that if you reference HttpServer.dll in any projects, you will need to change the reference to HttpServer_OpenSim.dll. It still uses the Same HttpServer namespace though.
