 Whenever you try to analyze the data and the pattern of
bandwidth usage in your network, you need to configure a data capturing software
between the proxy server and users. Sometimes it works as a sniffer, which can
make your network slow while running in a promiscuous mode. Charles Web Proxy
fixes up the problem by doing the job of a  proxy server and a data
capturing tool. Charles is an HTTP Proxy and Monitoring software that sits
between the Internet and the users and records all the traffic in every session
including requests, responses and the HTTP headers.

It shows the traffic in Structure and Sequence formats. It
features DNS Spoofing, Reverse Proxy, Port forwarding and automatic updates
among other features. It can be configured to provide any TCP/IP or UDP port

how it works.
