In computer networks, a proxy server is a server (a computer system or an application program) which services the requests of its clients by forwarding requests to other servers. A client connects to the proxy server, requesting some service, such as a file, connection, web page, or other resource, available from a different server. The proxy server provides the resource by connecting to the specified server and requesting the service on behalf of the client. A proxy server may optionally alter the client's request or the server's response, and sometimes it may serve the request without contacting the specified server. In this case, it would 'cache' the first request to the remote server, so it could save the information for later, and make everything as fast as possible. A proxy server that passes all requests and replies unmodified is usually called a gateway or sometimes tunneling proxy. A proxy server can be placed in the user's local computer or at specific key points between the user and the destination servers or the Internet.

Digital (SLR) photo

When we talked about digital camera, last thing that I remember is when I buy my new camera was really disappointed me, I never realize that knowing detail of the specification is one of the important thing to buy a digital camera.

For the second time I buy a new camera but this time I Follow my instinct and I asked a several question about Canon EOS 350D, Nikon D80 and Sony DSC-S730. I mention thre of different type of the digital camera because I know the information about it from here and I decide to buy one of my favorite Nikon D80 and it help me much for my works.

Well I did not made a wrong decision when I chose Nikon D80 all the specification is amazing, I can use long lenses to bring that distant person. The picture is seem really look closer and for the result I am really satisfied using this digital camera.
