Fiddler 4.6.20172.31233

Fiddler is a debugging proxy tool that will help you debug traffic from your Windows computer, Mac or Linux systems and even mobile devices. This small application is able to support any system, device or framework (including Java, .NET and Ruby).

Fiddler will also display information such as "total page weight and HTTP protocol caching or compression, allowing you to isolate performance barriers by applying rules like "Flag any uncompressed responses larger than 25kb."

This small application will also log all HTTP traffic among you computer and the World Wide Web. You can use it to reduce the number of bugs from traffic from almost any application that is using a proxy like Internet Explorer, Safari, Chrome, Opera, Firefox, and other browsers.

You can use Fiddler to test your security of web applications, decrypting HTTPS traffic, or displaying and modifying requests using the "man-in-the-middle" decryption method. Also Fiddler gives you the option to configure it in order to decrypt all traffic, or only the specific sessions.
