Inspect Traffic

With traffic already captured, the process of analyzing has begun. The first place where we can extract information about the captured sessions is the Live Traffic. Each session (a session is the request/response entry) is listed in a row with multiple column fields in the sessions list. You can extract useful information like the returned status code, the host and the URL, type of used protocol (HTTP vs. HTTPS), body sizer in bytes, used HTTP method (like GET or POST), and more.

Select a session (by clicking on the session row) to open additional information about the session request and response in the Fiddler inspectors. The request and response inspectors are powerful tools that will allow you to deep-dive in each session so you and your teammates can debug it or find performance bottlenecks.

In case, the HTTPS capturing is enabled, and the Decode option is activated, you will also be able to analyze encoded content (removes all HTTP Content and Transfer encoding from requests and responses).

Save a selected session or multiple selected sessions via the context menu (alternatively via a keyboard shortcut). Saved sessions are available in the Sessions list from which they can be reloaded or shared with collaborators.

Inspecting sessions is often done with teammates or external collaborators. Share a selected session or multiple selected sessions directly from the Live Traffic list or via the Sessions list.
