CustomRequestLog.java

Hi guys,
I'm finalizing the implementation of CustomRequestLog.java, basically
an implementation of the functionality contained in Apache's mod_log_config.
The parser for the log-format string is finished and the main loop to create
the log entry too. The problem I am now facing (due to my inexperience with
Jetty) is that I don't know how to get at the following information from
HttpRequest and/or HttpResponse (excerpt from
http://httpd.apache.org/docs/mod/mog_log_config.html):

%...a:          Remote IP-address
%...A:          Local IP-address
%...B:          Bytes sent, excluding HTTP headers.
%...b:          Bytes sent, excluding HTTP headers. In CLF format
        i.e. a '-' rather than a 0 when no bytes are sent.
%...c:          Connection status when response was completed.
                'X' = connection aborted before the response completed.
                '+' = connection may be kept alive after the response is sent.
                '-' = connection will be closed after the response is sent.
%...{FOOBAR}e:  The contents of the environment variable FOOBAR
%...f:          Filename
%...h:          Remote host
%...H       The request protocol
%...{Foobar}i:  The contents of Foobar: header line(s) in the request
                sent to the server.
%...l:          Remote logname (from identd, if supplied)
%...m       The request method
%...{Foobar}n:  The contents of note "Foobar" from another module.
%...{Foobar}o:  The contents of Foobar: header line(s) in the reply.
%...p:          The canonical Port of the server serving the request
%...P:          The process ID of the child that serviced the request.
%...q       The query string (prepended with a ? if a query string exists,
        otherwise an empty string)
%...r:          First line of request
%...s:          Status.  For requests that got internally redirected, this is
                the status of the *original* request --- %...>s for the last.
%...t:          Time, in common log format time format (standard english format
)
%...{format}t:  The time, in the form given by format, which should
                be in strftime(3) format. (potentially localized)
%...T:          The time taken to serve the request, in seconds.
%...u:          Remote user (from auth; may be bogus if return status (%s) is 4
01)
%...U:          The URL path requested, not including any query string.
%...v:          The canonical ServerName of the server serving the request.
%...V:          The server name according to the UseCanonicalName setting.


Done sofar:
%...a: use request.getRemoteAddr()
%...A: use InetAddress.getByName(request.getHost()) (inefficient??)
%...B: use responseLength
%...b: use responseLength
%...c: don't know (maybe response.getState() in conjunction with
       response.getField(HttpFields.__KeepAlive) ??)
%...{Foobar}e: use System.getProperty("Foobar") or ignore
%...f: don't know
%...h: use request.getRemoteHost()
%...H: use request.getScheme()
%...{Foobar}i: use request.getField("Foobar")
%...l: don't know
%...m: use request.getMethod()
%...{Foobar}n: ignored (do Handlers communicate anything usefull??)
%...{Foobar}o: use response.getField("Foobar")
%...p: use request.getPort()
%...P: don't know is there a System.getProperty("java.process.id")?
%...q: use request.getQuery()
%...r: don't know
%...s: don't know use response.getStatus()??
%...t: use request.getTimeStamp() and java.util.Calendar et.al.
%...T: don't know maybe request.getTimeStamp() with System.currentTimeMillis()?
%...u: use request.getAuthUser() (or request.getUserPrincipal().getName()??)
%...U: use request.getRequestURL()
%...v: use request.getHost() ??
%...V: use request.getHost() ??

If anybody could assist and let me know if any of my assumptions are wrong
or knows how to get at the missing information, I'd be gratefull :-)
Once this is finished and tested, would anybody else be interested in it?
If yes, I could donate it to Jetty if someone would explain the procedure.
Regards, Chris.
