> Changes by Simon Foster:
      - Split module up into to sepearate Network.[Stream,TCP,HTTP] modules
      - Created functions receiveHTTP and responseHTTP to allow server side interactions
        (although 100-continue is unsupported and I haven't checked for standard compliancy).
      - Pulled the transfer functions from sendHTTP to global scope to allow access by
        above functions.
</LI
><LI
> Changes by Graham Klyne:
      - export httpVersion
      - use new URI module (similar to old, but uses revised URI datatype)
</LI
><LI
> Changes by Bjorn Bringert:
</LI
><LI
> handle URIs with a port number
      - added debugging toggle
      - disabled 100-continue transfers to get HTTP/1.0 compatibility
      - change ioError to throw
      - Added simpleHTTP_, which takes a stream argument.
</LI
><LI
> Changes from 0.1
      - change openHTTP to <TT
><A HREF="Network-TCP.html#v%3AopenTCP"
>openTCP</A
></TT
>, removed closeTCP - use <TT
><A HREF="Network-Stream.html#v%3Aclose"
>close</A
></TT
> from <TT
><A HREF="Network-Stream.html#t%3AStream"
>Stream</A
></TT
> class.
      - added use of inet_addr to openHTTP, allowing use of IP <A HREF="dot.html"
>dot</A
> notation addresses.
      - reworking of the use of Stream, including alterations to make <TT
><A HREF="Network-HTTP.html#v%3AsendHTTP"
>sendHTTP</A
></TT
> generic
        and the addition of a debugging stream.
      - simplified error handling.
</LI
><LI
> TODO
     - request pipelining
     - https upgrade (includes full TLS, i.e. SSL, implementation)
         - use of Stream classes will pay off
         - consider C implementation of encryption/decryption
     - comm timeouts
     - MIME &amp; entity stuff (happening in separate module)
     - support &quot;*&quot; uri-request-string for OPTIONS request method

>Host</TT
></DT
><DD
>
                  Required by HTTP/1.1, if not supplied as part
                  of a request a default Host value is extracted
                  from the request-uri.
</DD

>Connection</TT
></DT
><DD
> 
                  If this header is present in any request or
                  response, and it's value is <A HREF="close.html"
>close</A
>, then
                  the current request/response is the last 
                  to be allowed on that connection.
</DD
><DT
><TT
>Expect</TT
></DT
><DD
>
                  Should a request contain a body, an Expect
                  header will be added to the request.  The added
                  header has the value &quot;100-continue&quot;.  After
                  a 417 &quot;Expectation Failed&quot; response the request
                  is attempted again without this added Expect
                  header.
</DD
><DT

>TransferEncoding,ContentLength,...</TT
></DT
><DD
>
                  if request is inconsistent with any of these
                  header values then you may not receive any response
                  or will generate an error response (probably 4xx).

 Some response codes induce special behaviour:
</LI
></UL
><DL
><DT
><TT
>1xx</TT
></DT
><DD
>   &quot;100 Continue&quot; will cause any unsent request body to be sent.
             &quot;101 Upgrade&quot; will be returned.
             Other 1xx responses are ignored.
</DD
><DT
><TT
>417</TT
></DT
><DD
>   The reason for this code is &quot;Expectation failed&quot;, indicating
             that the server did not like the Expect &quot;100-continue&quot; header
             added to a request.  Receipt of 417 will induce another
             request attempt (without Expect header), unless no Expect header
             had been added (in which case 417 response is returned).
