It can also forward data through external commands (for logging, filtering or copying network traffic). It is written in ANSI C so it takes a very little space and can be used on embedded devices.

+## Parsers
+
 Input parser and output parser are commands through which incoming and outgoing packets can be forwarded. For example to use a "tee" command to log all incoming http data to incoming.txt file you can start proxy with the following options:
 ```
 proxy -l 8080 -h 192.168.1.2 -p 80 -i "tee -a input.log" -o "tee -a output.log"

 ## Advanced usage
 
+### Using parsers to copy network traffic to multiple hosts
+
 You can use input and output parsers to copy incoming / outgoing traffic to other hosts (e.g. for monitoring reasons). Just use "tee" command to copy network packets to named pipes and then read from those pipes.
 
 The following scenario assumes you set up the program on local port 8080 as a proxy to www.wikipedia.org, and copy all outgoing requests to servers listening on ports 9000 and 9001 on localhost.

 **Important notice:** Make sure to read data from all the pipes. If you don't, tee will stuck on writing to the pipe which is not being read from, and so the proxy will be stuck also. Also if you restart a listener, netcat may not reconnect to it, which means that you will need to restart the appropriate forwarder script, too.
