<p>QNetworkProxy provides the method for configuring network layer
proxy support to the Qt network classes. The currently supported
classes are <a href="qabstractsocket.html">QAbstractSocket</a>,
<a href="qtcpsocket.html">QTcpSocket</a>, <a href="qudpsocket.html">QUdpSocket</a>, <a href="qtcpserver.html">QTcpServer</a>, <a href="qnetworkaccessmanager.html">QNetworkAccessManager</a> and <a href="qftp.html">QFtp</a>. The proxy support is designed to be as
transparent as possible. This means that existing network-enabled
applications that you have written should automatically support
network proxy using the following code.</p>
<pre class="cpp">
<span class="type">QNetworkProxy</span> proxy;
proxy<span class="operator">.</span><a href="qnetworkproxy.html#setType">setType</a>(<span class="type">QNetworkProxy</span><span class="operator">.</span>Socks5Proxy);
proxy<span class="operator">.</span><a href="qnetworkproxy.html#setHostName">setHostName</a>(<span class="string">"proxy.example.com"</span>);
proxy<span class="operator">.</span><a href="qnetworkproxy.html#setPort">setPort</a>(<span class="number">1080</span>);
proxy<span class="operator">.</span><a href="qnetworkproxy.html#setUser">setUser</a>(<span class="string">"username"</span>);
proxy<span class="operator">.</span><a href="qnetworkproxy.html#setPassword">setPassword</a>(<span class="string">"password"</span>);
<span class="type">QNetworkProxy</span><span class="operator">.</span><a href="qnetworkproxy.html#setApplicationProxy">setApplicationProxy</a>(proxy);
</pre>
<p>An alternative to setting an application wide proxy is to
specify the proxy for individual sockets using <a href="qabstractsocket.html#setProxy">QAbstractSocket.setProxy</a>() and
<a href="qtcpserver.html#setProxy">QTcpServer.setProxy</a>(). In
this way, it is possible to disable the use of a proxy for specific
sockets using the following code:</p>
<pre class="cpp">
serverSocket<span class="operator">-</span><span class="operator">></span>setProxy(<span class="type">QNetworkProxy</span><span class="operator">.</span>NoProxy);
</pre>
<p>Network proxy is not used if the address used in <a href="qabstractsocket.html#connectToHost">connectToHost()</a>, <a href="qudpsocket.html#bind">bind()</a> or <a href="qtcpserver.html#listen">listen()</a> is equivalent to <a href="qhostaddress.html#SpecialAddress-enum">QHostAddress.LocalHost</a>
or <a href="qhostaddress.html#SpecialAddress-enum">QHostAddress.LocalHostIPv6</a>.</p>
<p>Each type of proxy support has certain restrictions associated
with it. You should read the <a href="qnetworkproxy.html#ProxyType-enum">ProxyType</a> documentation
carefully before selecting a proxy type to use.</p>
<p><b>Note:</b> Changes made to currently connected sockets do not
take effect. If you need to change a connected socket, you should
reconnect it.</p>
<a id="socks5" name="socks5" />
<h3>SOCKS5</h3>
<p>The SOCKS5 support in Qt 4 is based on <a href="http://www.rfc-editor.org/rfc/rfc1928.txt">RFC 1928</a> and
<a href="http://www.rfc-editor.org/rfc/rfc1929.txt">RFC 1929</a>.
The supported authentication methods are no authentication and
username/password authentication. Both IPv4 and IPv6 are supported.
Domain names are resolved through the SOCKS5 server if the <a href="qnetworkproxy.html#Capability-enum">QNetworkProxy.HostNameLookupCapability</a>
is enabled, otherwise they are resolved locally and the IP address
is sent to the server. There are several things to remember when
using SOCKS5 with <a href="qudpsocket.html">QUdpSocket</a> and
<a href="qtcpserver.html">QTcpServer</a>:</p>
<p>With <a href="qudpsocket.html">QUdpSocket</a>, a call to
<a href="qudpsocket.html#bind">bind()</a> may fail with a timeout
error. If a port number other than 0 is passed to <a href="qudpsocket.html#bind">bind()</a>, it is not guaranteed that it is
the specified port that will be used. Use <a href="qabstractsocket.html#localPort">localPort()</a> and <a href="qabstractsocket.html#localAddress">localAddress()</a> to get the
actual address and port number in use. Because proxied UDP goes
through two UDP connections, it is more likely that packets will be
dropped.</p>
<p>With <a href="qtcpserver.html">QTcpServer</a> a call to <a href="qtcpserver.html#listen">listen()</a> may fail with a timeout
error. If a port number other than 0 is passed to <a href="qtcpserver.html#listen">listen()</a>, then it is not guaranteed
that it is the specified port that will be used. Use <a href="qtcpserver.html#serverPort">serverPort()</a> and <a href="qtcpserver.html#serverAddress">serverAddress()</a> to get the
actual address and port used to listen for connections. SOCKS5 only
supports one accepted connection per call to <a href="qtcpserver.html#listen">listen()</a>, and each call is likely to
result in a different <a href="qtcpserver.html#serverPort">serverPort()</a> being used.</p>
<hr /><h2>Type Documentation</h2><h3 class="fn"><a name="Capability-enum" />QNetworkProxy.Capability</h3><p>These flags indicate the capabilities that a given proxy server
supports.</p>
<p><a href="qnetworkproxy.html">QNetworkProxy</a> sets different
capabilities by default when the object is created (see <a href="qnetworkproxy.html#ProxyType-enum">QNetworkProxy.ProxyType</a>
for a list of the defaults). However, it is possible to change the
capabitilies after the object has been created with <a href="qnetworkproxy.html#setCapabilities">setCapabilities</a>().</p>
<p>The capabilities that <a href="qnetworkproxy.html">QNetworkProxy</a> supports are:</p>

combination of Capability values.</p>
<h3 class="fn"><a name="ProxyType-enum" />QNetworkProxy.ProxyType</h3><p>This enum describes the types of network proxying provided in
Qt.</p>
<p>There are two types of proxies that Qt understands: transparent
proxies and caching proxies. The first group consists of proxies
that can handle any arbitrary data transfer, while the second can
only handle specific requests. The caching proxies only make sense
for the specific classes where they can be used.</p>

Qt 4.5 it is possible to remove the capability of caching from a
proxy by calling <a href="qnetworkproxy.html#setCapabilities">setCapabilities</a>().</p>
