These programs receive &HTTP; and &FTP; requests, retrieve the relevant files from the internet, and pass them on to the client computer that made the requests.</para> <para>When you have configured a proxy, &HTTP; and/or &FTP; requests are re-routed through the computer that is acting as a proxy server. However, you can also select specific hosts which should be contacted directly, rather than through the proxy server. If you are on a local network, for example, access to local hosts probably doesn't need to go through a proxy server.</para> <para>You should only need to configure a proxy server if your network administrator requires it (if you are a dial-up user, that would be your internet service provider or <acronym>ISP</acronym>). Otherwise, especially if you are feeling a bit confused about this proxy business, but everything seems to be fine with your internet connection, you don't need to change anything.</para> <para>Please note that using proxy servers is optional, but has the benefit or advantage of giving you faster access to data on the internet.</para> <para>If you are uncertain whether or not you need to use a proxy server to connect to the internet, please consult with your internet service provider's setup guide or your system administrator.</para> </sect2> <sect2 id="proxies-use"> <title>Use</title> <variablelist> <varlistentry> <term><guilabel>Connect to the Internet directly</guilabel></term> <listitem> <para>Select this option if you do <emphasis>not</emphasis> want to use a proxy server.</para> </listitem> </varlistentry> </variablelist> <para>If you have decided to use a proxy, you have several methods to configure the settings for it.</para> <variablelist> <varlistentry> <term><guilabel>Automatically detected script file</guilabel></term> <listitem> <para>Select this option if you want the proxy setup configuration script file to be automatically detected and downloaded.</para> <para>This option only differs from the next choice in that it <emphasis>does not</emphasis> require you to supply the location of the configuration script file.
