How to listen for inbound traffic with Netcat?

Hello,

I am looking for a tool that logs all the traffic that occurs on a
specified port of my server (in particular the http port).

When I use netcat with the following syntax: "C:\netcat>nc.exe -l
-p 80" I get "Can't grab 0.0.0.0:80 with bind" error if a web server
already listens to that port. If I stop the web server netcat runs
successfully but that's not what I want. I need to listen, with the
web server started, so that I can log the information that is received
AND sent on that port. Is this possible? Could you please point me to
some tools that could do this if there are any?

P.S. I use Windows but Unix tools are also welcome.

Great, but what has your question to do with "Networking and
communications under Linux."?
