These programs receive <acronym class="acronym">HTTP</acronym> and <acronym class="acronym">FTP</acronym> requests, retrieve the relevant files from the internet, and pass them on to the client computer that made the requests.</p><p>When you have configured a proxy, <acronym class="acronym">HTTP</acronym> and/or <acronym class="acronym">FTP</acronym> 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.</p><p>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 class="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.</p><p>Please note that using proxy servers is optional, but has the benefit or advantage of giving you faster access to data on the internet.</p><p>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.</p></div><div class="sect2"><div class="titlepage"><div><div><h3 class="title"><a name="proxies-use"></a>Use</h3></div></div></div><div class="variablelist"><dl class="variablelist"><dt><span class="term"><span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">No Proxy</span></span></span></dt><dd><p>Select this option if you do <span class="emphasis"><em>not</em></span> want to use a proxy server and connect to the Internet directly.</p></dd></dl></div><p>If you have decided to use a proxy, you have several methods to configure the settings for it.</p><div class="variablelist"><dl class="variablelist"><dt><span class="term"><span xmlns:doc="http://nwalsh.com/xsl/documentation/1.0" class="guiitem"><span class="guilabel">Detect proxy configuration automatically</span></span></span></dt><dd><p>Select this option if you want the proxy setup configuration script file to be automatically detected and downloaded.</p><p>This option only differs from the next choice in that it <span class="emphasis"><em>does not</em></span> require you to supply the location of the configuration script file.
