Now Tomcat is also a cool pojo application server

David, have you looked at this...
https://tcpmon.dev.java.net/source/browse/tcpmon/
Its going to be easy... because it almost does what you want already.
It does mean that in TC you will change the connector port to say 8081
But the clients will still see 8080
ie [Client whether that be Browser or Apache] --- 8080[Billing
System]8081 ----- [TC]
So you dont mess with TC's internal stable code (what are you going to do
with the data if you do that?).... keep it outside.
Ig start writing reports to disk from TC's buffer socket.... I think you
going to kill TC's performance, so then you going to want to sneak the data
into a filter or create a special header.... oh boy!
Now... if you build your tunnel (Billing System) in a servlet....
From your admin port say (8085) you from a browser, simple start/stop
Billing System.
As soon as that happens clients can see TC, and if the billing system is
off.... clients are off.
Then you also have a way to get data.... you can ask the Billing System...
how many bytes for Client IP xyz (its a servlet), etc.
When you business get huge with load sharing and remote offices.... the
billing system is just a servlet, so its easy.
I would keep it outside of TC.... but put it in a servlet.
If you CVS that swoftware down I think you going to find the relay socket
logic is probably 30 lines of code... it listens and forwards, cant be too
bad...
And then... if you want (unlikely) you embed your special servlet in TC, and
add some xml configuration...
My 1/2 cent worth ;)

I took a look at lamdaprobe but it only counts the payload and not the
HTTP request.
Back to my original question.....can anyone help?

Well it should works since the Lamba Probe, got these numbers for HTTP
and AJP.

2007/10/25, Dave Rathnow <[EMAIL PROTECTED]>:
Hello Again,
I was wondering if someone could give me some help with this. I think
using a connector is probably the way to go to solve this problem;
however, I'm not sure where to start. How do I create my own
connector and the plumb it into Tomcat so it will be used. I will be
using a separate port other than 8080 for the devices that will be
sending and receiveing data so, if possible, I would like to leave the
default connector on port 8080.
Again, I don't want to reimplement the code that parses the HTTP. All
I need to do is count the number of bytes arriving and being sent so
if I can reuse code from an existing connector, that would be great.
Thanks,
Dave.

Well, if you want absolute byte - connector seems the only place,
there are space and tabs beeing skipped when parsing headers, etc.
If you are ok with an estimate - the AccessLogValve is ok, add all the
header lengths + method + http/1.1. You'll miss bytes for encodings,
spaces.
Re. where to add - each connector is different on how it reads/parse
the message, you probably want to do it close to the 'read()' call,
save it somewhere associated with the request ( a note or attribute )
and read it in a valve or filter.
