Charles Proxy a popular web debugging proxy tool
We can define "Charles proxy" as an interactive web debugging tool that acts as a middleware between the mobile or web app and the internet resources. By using this tool we can configure client environment to pass all networking requests and responses through Charles proxy so that we can inspect and even change the data midstream to test how the app responds.

Charles Proxy Key Features
Traffic Monitoring: Charles Proxy acts as an intermediary between the client and the server, capturing and displaying all HTTP/HTTPS traffic in real-time. It allows you to view the details of each request and response, including headers, parameters, cookies, and content.
SSL Proxying: Charles Proxy has the capability to intercept and decrypt HTTPS traffic, enabling you to inspect and analyze secure communications between the client and the server. This feature is particularly useful for debugging and troubleshooting secure connections.
Request/Response Modification: Charles Proxy allows you to modify and manipulate the requests and responses in real-time. You can add, edit, or remove headers, modify parameters, simulate different response codes, and test various scenarios to analyze the behavior of the client or server.
Bandwidth Throttling: With Charles Proxy, you can simulate different network conditions by throttling the network bandwidth. This feature helps in testing and analyzing the performance of a mobile app under different network speeds or unstable network conditions.
Repeat and Edit Requests: Charles Proxy allows you to repeat or resend specific requests to the server for testing and debugging purposes. You can also edit the requests before resending them, making it easier to test different scenarios or parameters.
Remote Debugging: Charles Proxy supports remote debugging, enabling you to capture and analyze network traffic from devices connected to the same network. This is particularly useful for testing mobile apps on real devices during development or testing.
Breakpoints: Charles Proxy allows you to set breakpoints on specific requests or responses, pausing the communication flow. It enables you to analyze the traffic at a particular point, modify the request or response, and observe the application behavior.
Reporting and Logging: Charles Proxy provides detailed reports and logs of the captured network traffic, making it easier to analyze and document the communication between the client and the server. The logs can be exported in various formats for further analysis or sharing.
