If a user reaches the conclusion that they need to study the connections and traffic generated by visiting a website, the most likely explanation is that they are responsible for developing that site, or are dealing with some form of malware. There are many dedicated analysis tools, but if the main goal is simply to capture data, you might not need to look any further than FiddlerCap.
By clicking to read this article you have opened a certain number of connections that downloaded multiple elements besides the text that makes it up. This happens on every page you visit, and it is normal behavior. However, the general rule is that all those connections happen in the background, and browsers are not in the habit of providing specific information about them. To analyze Web traffic there are all kinds of programs, from simple log generators to the so-called "sniffers", with an enormous number of functions. A while ago I talked about Fiddler, one of the many options the market offers, which works as a "debugging proxy". Fiddler is very complete, and that detail might make it too intimidating for a novice user. That is when FiddlerCap appears.
FiddlerCap is nothing more than a Web traffic recorder. Load the program, press "Start Capture", visit the sites that are supposedly affected, and save the log, that is all. FiddlerCap offers functions to store binaries, decrypt HTTPS traffic and save cookies, but it does not go beyond that. Through its simplicity, FiddlerCap seeks to eliminate the intimidation factor of Fiddler, without losing the opportunity to obtain information that could help fix a problem. Once the capture is finished, all the user has to do is send the file with the .SAZ extension to someone willing to explore the data with Fiddler. Logs can become gigantic in a very short time, so you will need to agree on some method to transfer them in a stable and secure way.
Although it is not mandatory for FiddlerCap to be accompanied by Fiddler, their bond is too close to deny it. Anyone who has used TeamViewer in the past will understand the relationship better: if Fiddler were like TeamViewer, FiddlerCap would be similar to the QuickSupport module that simplifies the remote user's work. FiddlerCap is free, and its installer barely exceeds 300 kilobytes, so there are no distribution problems. Compatible only with Windows.
