Selamat datang di RAJA-DVD

Proxy adalah sebuah komputer server atau program komputer yang dapat bertindak sebagai komputer lainnya untuk melakukan request terhadap content dari Internet atau intranet.Proxy Server bertindak sebagai gateway terhadap dunia Internet untuk setiap komputer klien. Web server yang menerima request dari proxy server akan menginterpretasikan request-request tersebut seolah-olah request itu datang secara langsung dari komputer klien, bukan dari proxy server.
Proxy server juga dapat digunakan untuk mengamankan jaringan pribadi yang dihubungkan ke sebuah jaringan publik. Proxy server memiliki lebih banyak fungsi daripada router yang memiliki fitur packet filtering karena memang proxy server beroperasi pada level yang lebih tinggi dan memiliki kontrol yang lebih menyeluruh terhadap akses jaringan.
