Troubleshooting: Monitoring HTTP Communication Via Local HTTP Proxy

Troubleshooting lower-level HTTP communication issues can be challenging.  Before resorting to lower-level network packet tracing tools, using an in-process HTTP Proxy application simplifies troubleshooting.

Introducing Fiddler - HTTP Proxy Application

Fiddler2 is an HTTP troubleshooting tool that allows capturing the transfer of information over HTTP.  Fiddler provides the ability to intercept HTTPS communication by using a man-in-the-middle strategy by re-signing HTTP communication.  When configured, this allows for the troubleshooting of HTTPS data.

This tool is a preferred support tool used by developers and technicians at Riva when troubleshooting HTTP communication errors or invalid data.
