Live Traffic

The Live Traffic is an essential feature of Fiddler Everywhere - it displays a list of web sessions with summary of each session that the Fiddler Everywhere client has captured. Live Traffic

Many operations begin by selecting one or more entries in the Live Traffic and then activating other features.
