A reverse proxy is a proxy server that is installed in the neighborhood of one or more webservers. All traffic coming from the Internet and with destination one of the webservers is going through the proxy server. There are several reasons for installing reverse proxy servers: Security: the proxy server is an additional layer of defense and therefore protects the webservers further up the chain Encryption / SSL acceleration: when secure websites are created, the SSL encryption is often not done by the webserver itself, but by a reverse proxy that is equipped with SSL acceleration hardware. See Secure Sockets Layer. Load distribution: the reverse proxy can distribute the load to several webservers, each webserver serving its own application area. In such a case, the reverse proxy may need to have to rewrite the URLs in each webpage (translation from externally known URLs to the internal locations) Serve/cache static content: A reverse proxy can offload the webservers by ...

.NET Remoting Versus Web Services With the advent of .NET and the .NET Framework, Microsoft introduced a set of new technologies in the form of Web services and .NET remoting. .NET remoting and ASP.NET Web services are powerful technologies that provide a suitable framework for developing distributed applications. It is important to understand how both technologies work and then choose the one that is right for your application. The Web services technology enables cross-platform integration by using HTTP, XML and SOAP for communication thereby enabling true business-to-business application integrations across firewalls. Because Web services rely on industry standards to expose application functionality on the Internet, they are independent of programming language, platform and device. Remoting is .a technology that allows programs and software components to interact across application domains, processes, and machine boundaries. This enables your applications ...
