+...
+
+Introduction
+============
+
+It happens occasionally that I would like to use the XMPP server as a
+generic proxy for connecting to another service. It is especially
+awkward in some environments, and impossible in (for example) Javascript
+inside a web browser.
+
+Details
+=======
+
+Using mod\_tcpproxy an XMPP client (including those using BOSH) can
+initiate a pipe to a given TCP/IP address and port. This implementation
+uses the [In-Band Bytestreams](http://xmpp.org/extensions/xep-0047.html)
+XEP, simply extended with 2 new attributes in a new namespace, host and
+port.
+
+An example Javascript client can be found in the web/ directory of
+mod\_tcpproxy in the repository.
+
+Configuration
+=============
+
+Just add tcpproxy as a component, for example:
+
+`Component "tcp.example.com" "tcpproxy"`
+
+Protocol
+========
+
+A new stream is opened like this:
+
+    <iq type="set" id="newconn1" to="tcp.example.com">
+        <open xmlns='http://jabber.org/protocol/ibb'
+            sid='connection1'
+            stanza='message'
+            xmlns:tcp='http://prosody.im/protocol/tcpproxy'
+            tcp:host='example.com'
+            tcp:port='80' />
+    </iq>
+
+The stanza attribute (currently) MUST be 'message', and a block-size, if
+given, is (currently) ignored.
+
+In response to this stanza you will receive a result upon connection
+success, or an error if the connection failed. You can then send to the
+connection by sending message stanzas as described in the IBB XEP.
+Incoming data will likewise be delivered as messages.
+
