[v4.2] Charles – Cross-platform edge tool for web debugging proxy

In the common web application developing, testing and debugging process, developers need to figure out, analyze and eliminate all sorts of network problems by capturing the network communication packages (especially for those apps based on a server), and have a look at what they actually receive and send. At this time, Charles will come in handy.

Charles is a cross-platform web debugging (HTTP proxy server, HTTP monitor, Reverse proxy server) application written in Java. It is an acknowledged, very powerful network packets capturing and analyzing tool developed for Windows, Mac OS X and Linux platforms. By setting itself as a proxy server for system network access, Charles has all network access requests done through it, so as to realize the capture and analysis actions to network packets.

When the user's web browser connects to Charles proxy server to access the Internet, Charles can monitor all the data sent from and received by this browser. That's to say, Charles enables web or software developers to check all the HTTP and SSL/HTTPS communications between users' computer and Internet, including requests, responses, and HTTP headers (along with cookies and cache information).

When developing mobile applications, for example, we often need to capture network packets to analyze in order to debug the network communication protocol between client-side and server-side. After mastering Charles, you will basically be able to say goodbye to any other network sniffering tools. If you are using or ever used the Fiddler for free and cross-platform web debugging proxy solution, now you can switch to Charles - it's much better than Fiddler. In short, getting the most out of Charles is able to greatly facilitate the development and debugging work made for applications with network requests.
