Fiddler is a network analysis and debugger proxy used for logging the internet traffic between the computer and the internet. Inspect the network traffic, set breakpoints, and play around with the request and responses. Its main intention is to find network issues and loopholes between the connection from your computer to the internet. It comes with a new and improved user interface with an emphasis on simplifying the tasks. The latest API composer allows users to create mock requests and responses to a remotely accessible API. Collaborate with the team and share links to access sessions or for analyzing network traffic.

Fiddler Review and Overview

Debugging and finding out errors located in the network connections are tricky, especially when there are hundreds of computers connected to the same Local area network. It becomes more challenging to ensure the safety of the computers on the network. If one computer gets infected due to virus or malware, it might spread to other computers on the network. Fiddler uses enhanced network analysis as a proxy to prevent logging from the external systems. It can simulate the network requests and responses while the debugging process is carried out. Log the traffic and understand unauthorized connection requests that are being performed in the network. It has link sharing and collaborative features that may come in handy when they need to analyze the captured network traffic.

Continuous web debugging tools

The debug tools powered by Fiddler allows for continuous debugging and tracing network traffic from your computer to the internet. It can search and find out the IP addresses and log them to understand their original location. The web traffic debugging system is compatible with Windows, Android, and iOS platforms. It can detect cookies, cache, and codes embedded in JavaScript files that are transferred across the internet.

Use it to find out proper implementation of cookies, HTTP headers, and cache directives that should be transferred between the client and the webserver. It supports nearly every framework, including Java, Ruby, and .NET. Debugging these addresses enables them to find a mismatch between content that existed before and what is present right now.

Request and response mocking

It allows users to send requests to the server for connecting to a website and simulate the responses. By doing so, it analyzes the traffic and modifies the actual response and request accordingly. This makes it simple to change the code, and also the request and response parameters. In this method, there is no actual need to touch the source code of the requests.

This simulation method ensures that the software can anticipate the issues that may arise due to the malfunctioning code that might arrive via an HTTP response. Use Fiddler to track and record the traffic between the computer and the internet. Since it supports a variety of platforms, including Windows, Android, and iOS, the cross-compatibility is never an issue. Basically, any platform that supports a proxy server can be logged without any extra changes in the underlying system configuration.

Collaboration features of the proxy service

Fiddler supports collaboration services with team members over the internet. It has a link-sharing feature that lets users share their network traffic logs and raw data for analysis. Add more clarity to the data by adding comments and annotations to the files. Share the files to the receiver over the cloud infrastructure and enable read and edit access to complete the process.

Additional Tools from Fiddler

It has three components that form the backbone of the proxy suite. The first one being the original Fiddler network proxy tool that allows debugging of network traffic. The FiddlerCore is a .NET based library with all the functions of the proxy that can be integrated into third-party applications. FiddlerCap for capturing data from end-user environments or customer environments quickly.
