+<H3>
+Description</H3>
+SSLTap opens a socket on a rendezvous port, and waits for an incoming connection
+(client side). Once this connection arrives, SSLTap makes another connection
+to hostname:port (server side). It passes any data sent by the client to
+the server, and vice versa. However, SSLTap will also display the data
+to the console. It can do this for plain HTTP connections, or any TCP protocol.
+However, SSLTap can also work with SSL streams, as detailed below.
+
+<P>Let's assume your development machine is called 'intercept'. The simplest
+usage of SSLTap is to run the command <TT>'ssltap www.netscape.com:80'</TT>
+on intercept. The program will wait for an incoming connection on port
+1924. Next you would want to go to your browser, and enter the URL http://intercept:1924.
+The page retrieved by the browser will actually be gotten from the server
+at www.netscape.com, but will go via SSLTap.
+
+<P>Data sent from the client to the server is surrounded by a '--> [ ]'
+symbol, and data sent from the server to the client, a '&lt;---[&nbsp;
+]' symbol.
+
+<P>You'll notice that the page retrieved with this example looks incomplete.
+This is because SSLTap by default closes down after the first connection
+is complete, so the browser is not able to load images. To make the SSLTap
+continue to accept connections, switch on looping mode with the -l option.
+
+<P>You can change the default rendezvous port to something else with the
+-p option.
+
+<P>The remaining options change the way the output is produced.
+
+<P>The -f option prints 'fancy' output - in colored HTML. Data sent from
+the client to the server is in blue. The server's reply is in red. This
+is designed so you can load the output up into a browser. When used with
+looping mode, the different connections are separated with horizontal lines.
+
+<P>-x will turn on HEX printing. Instead of being output as ascii, the
+data is shown as Hex, like this:
+<UL><TT>&lt;-- [</TT>
+<BR><TT>&nbsp;&nbsp; 0: 56 d5 16 3e&nbsp; a1 6b b1 4a&nbsp; 8f 67 c4 d7&nbsp;
+21 2f 6f dd&nbsp; | V..>.k.J.g..!/o.</TT>

+<BR><TT>]</TT>
+<BR>&nbsp;</UL>
+
+<H4>
+SSL Parse mode</H4>
+The following options deal with SSL connections.
+<UL>-s will turn on SSL parsing. (SSLTap doesn't automatically detect SSL
+sessions.)
+<BR>-x will turn on extra SSL hexdumps. Mostly, if SSL can decode the data,
+it doesn't display the hex.</UL>
+The following SSL3 Data structures are parsed: Handshake, ClientHello,
+ServerHello, CertificateChain, Certificate. In addition, SSL2 ClientHello,
+ServerHello, ClientMasterKey are also partly parsed. NO DECRYPTION IS PERFORMED
+ON THE DATA. SSLTAP CANNOT DECRYPT the data.
+
+<P>If a certificate chain is detected, DER-encoded certificates will be
+saved into files in the current directory called 'cert.0x' where x is the
+sequence number of the certificate.
+<BR>&nbsp;
+<H3>
+Operation Hints</H3>
+Often, you'll find that the server certificate does not get transferred,
+or other parts of the handshake do not happen. This is because the browser
+is taking advantage of session-id-reuse (using the handshake results from
+a previous session). If you restart the browser, it'll clear the session
+id cache.
+
+<P>If you run the ssltap on a different machine that the ssl server you're
+trying to connect to, the browser will complain that the host name you're
+trying to connect to is different to the certificate, but it will still
+let you connect, after showing you a dialog.
