Charles - sniffer, debugger and proxy server in one "package". Charles is installed as a proxy server and allows you to monitor the packets sent and received between the servers and your Internet applications. First of all, it will be interesting for software developers and server administrators, because without such tools it is very difficult to get things right.

Charles acts as an intermediary not only in http connections, but also in encrypted SSL channels. All requests can be viewed in plain text. This way, you will be able to debug your HTTPS session.

The modem simulation features allow you to test your site for users with low speed internet access. Charles narrows the channel by simulating any bandwidth.

This debugger is well suited for XML development, particularly when working with Asynchronous Javascript and XML (AJAX) and XMLHTTP. You can visually view the data that passes from server to client, and vice versa. Charles supports JSON, JSON-RPC and SOAP by default, displaying each of them in a simple tree form.

When installing a proxy server, the program can automatically change proxy settings in most Windows and Mac OS X browsers.
