• Key Features and Functions

    A program for detailed analysis of network traffic, which is an advanced proxy server. Capable of tracking all information sent to the Internet by a browser or any other program. Can be used to hack online games.

    The main purpose of the utility is the ability to monitor all network data sent or received by the computer. Includes three main functions: sniffer (traffic analysis), debugger (search for errors) and proxy server (intermediate entry point into the network).

    The program contains a large number of tools that will be useful to server administrators, developers of various software and webmasters. Charles is popular among ordinary users because of the ability to “intervene” in the dialogue between the game and the online server. This is often used by “cheaters” (lovers of dishonest play).

    Key Features:

    • an advanced proxy server that is quite easy to use;
    • traffic analyzer;
    • the ability to eliminate errors at the server-client stage;
    • emulation of low-speed Internet connection;
    • customizable reporting type.

    Working principle:

    The average user is unlikely to be able to immediately understand the functionality of Charles. Therefore, we recommend that you familiarize yourself with the training material, which is available on YouTube.

    The most common purpose of downloading a program is to change values ​​when playing online. To do this, when there is an active Internet session, traffic analysis is launched (a button with a camera image). The “Structure” tab displays a tree of active requests. You can open the required section by right-clicking and selecting “Advanced Repeat”. After which you will have access to the window for changing the value of any of these requests. Typically, this is the algorithm used to hack online applications.

    Pros:

    • really great functionality for creating a proxy server;
    • stability at work.

    Cons:

    • requires certain knowledge for full use;
    • no Russian localization;
    • high license cost.

    A big plus for Charlis is that although the program cannot be downloaded for free in Russian, its English Trial version is available without restrictions in functionality for 30 days. But the cost of a full-fledged version of the application is quite high - from $50 for a personal license to $700 for a fully functional “unlimited” server license. On the other hand, such software has never been cheap, and during the trial period you can decide on the advisability of further use of the utility.

    Analogues:

    Fiddler2 is a free traffic monitoring program;

    Apache HTTP Server - software for deploying a proxy server on a computer.

    Charles is an HTTP proxy / HTTP monitor / Reverse Proxy that enables a developer to view all of the HTTP and SSL / HTTPS traffic between their machine and the Internet. This includes requests, responses and the HTTP headers (which contain the cookies and caching information).

    Charles is a web proxy (HTTP Proxy / HTTP Monitor) that runs on your own computer. Your web browser (or any other Internet application) is then configured to access the Internet through Charles, and Charles is then able to record and display for you all of the data that is sent and received.

    In Web and Internet development you are unable to see what is being sent and received between your web browser / client and the server. Without visibility this it is difficult and time-consuming to determine exactly where the fault is. Charles makes it easy to see what is happening, so you can quickly diagnose and fix problems.

    Charles makes debugging quick, reliable and advanced; saving you time and frustration!

    SSL Proxying – view SSL requests and responses in plain text
    Charles can act as a man-in-the-middle for HTTP/SSL communication, enabling you to debug the content of your HTTPS sessions.

    Bandwidth Throttling to simulate slower Internet connections including latency
    Charles simulates modem speeds by effectively throttling your bandwidth and introducing latency, so that you can experience an entire website as a modem user might (bandwidth simulator).

    AJAX debugging – view XML and JSON requests and responses as a tree or as text
    Charles is useful for XML development in web browsers, such as AJAX (Asynchronous Javascript and XML) and XMLHTTP, as it enables you to see the actual XML that is flowing between the client and the server. Charles natively supports JSON, JSON-RPC and SOAP; displaying each in a simplified tree format for easy viewing and debugging.

    AMF – view the contents of Flash Remoting / Flex Remoting messages as a tree
    Charles is great for Adobe Flash developers as you can view the contents of LoadVariables, LoadMovie and XML loads. Charles also has native support for Flash Remoting (AMF0 and AMF3).

    Repeat requests to test back-end changes

    Edit requests to test different inputs

    Breakpoints to intercept and edit requests or responses

    Validate recorded HTML, CSS and RSS/atom responses using the W3C validator

    Autoconfigure Browser & System Proxy Settings

    Charles will autoconfigure your browser's proxy settings on the following browsers:

    Windows system proxy settings (includes Internet Explorer and most other applications)
    - Mac OS X system proxy settings (includes Safari and most other applications)
    - Mozilla Firefox (on all platforms)

    Charles is a 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 servers and your Internet applications. First of all, this will be of interest to software developers and server administrators, because without such tools it is very difficult to establish proper operation.

    Charles acts as an intermediary not only in HTTP connections, but also in SSL encrypted channels. You can view all requests in plain text. This way you will be able to debug HTTPS sessions.

    Features that simulate modem connections will allow you to test your site for users with low-speed Internet. Charles narrows the channel, simulating any bandwidth.

    This debugger is well suited for XML development, in particular when working with AJAX (Asynchronous Javascript and XML) and XMLHTTP. You can visually view the data that passes from the server to the 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 browsers on Windows and Mac OS X platforms.

    Key Features and Functions

    • SSL Proxying - ability to view SSL requests and responses in text format;
    • ability to set channel width. This is necessary in order to simulate a slow Internet connection, including data transfer delays;
    • AJAX debugging - ability to view XML and JSON requests and responses in tree or text format;
    • AMF - viewing the contents of Flash Remoting / Flex Remoting messages in a tree format;
    • Repeat requests to test back-end changes - repeat requests to test changes;
    • editing queries to test different connections;
    • Breakpoints to intercept and edit requests or responses - the ability to intercept and edit requests and responses;
    • Validate recorded HTML, CSS and RSS/atom responses using the W3C validator - the ability to validate recorded HTML, CSS and RSS/Atom responses using the W3C validator.
