Playback LoadRunner through Fiddler

If you are concerned that your LoadRunner script is not emulating user behaviour correctly and want to make sure it is download all the correct files etc, then you can connect LoadRunner to Fiddler and play the script so that fiddler captures the HTTP calls. For those that don’t know Fiddler is a debugging proxy that captures and displays the HTTP requests between a browser and the server (it does more but that is a quick summary). An example output is shown below:

You can then run VuGen or (don’t do it at load) through the controller by setting the proxy under runtime options.
