Scenario 2.2: Proxy Error
=========================

Purpose
-------

Identify the propagation of performance issues throughout a system by correlating error status codes across component services.

Description
-----------

This demonstration shows how decrypted traffic can be utilized in tandem with a network proxy to provide visibility into network operations.

Procedure
---------

1. Use a browser to navigate to the URL of the testapp server behind a network proxy.
2. Observe the decrypted traffic in NetScout's Packet Analysis tool.

Expected Outcome
----------------

The decrypted traffic is visible in NetScout despite the use of a network proxy.
