Not sure which file is being swapped out?

Try adding a custom column to the Web Sessions view of Fiddler for the Response Header of x-imposter. You can see Telerik's excellent documentation on how to add a column here: Configure Columns > Add Custom Columns. The x-imposter header is attached to every request that is successfully matched and swapped for a local file. The header contains the path of the file that was used to replace the requested file.

Not seeing your file be requested?

This usually happens when your file is being cached. You can disable your browser cache to alleviate this concern.

For Chrome

1. Open the Developer Tools.
2. Click on the Settings Gear in the upper right of the Developer Tools window.
3. In the popover, check "Disable cache (while DevTools is open).
4. Leave Developer Tools open and refresh the page.

For Internet Explorer (IE11)

1. Open the Developer Tools.
2. Go to the Network Tab (Ctrl+4).
3. From the top command bar, ensure the third button from the left is toggled on. If you mouseover the icon it should say "Always refresh from server". Note: If that is not working for whatever reason, the fourth button from the left on the Network Tab will clear the browser cache.
4. Refresh the page.
