Is is possible to add a rule to Fiddler so that it uses a local file instead of the online version?
There's a GET to /something/somefile.swf that is always made, but I need to use mylocalversion.swf
Thanks

  • https://stackoverflow.com/a/24774508/10245 shows how to use AutoResponders to do this for full hosts, this also works for serving from the filesyetem. – Tim Abell Sep 08 '17 at 16:24

You can absolutely use FiddlerScript for this, but the task you're describing is exactly what the AutoResponder feature was designed for.

  • How would you achieve this using FiddlerScript? The AutoResponder works fine in most cases, but in my case I need to mock an entire folder where file names have spaces, so even a regex backreference is not sufficient because instances of "%20" need to be replaced by " ". Seems like FiddlerScript only accept http, https, or ftp; hence my question on how you could use FiddlerScript to return a local file (without a local server). – Ama Sep 14 '20 at 11:25

    Set the `x-replywithfile` flag on the Session; see https://docs.telerik.com/fiddler/knowledgebase/fiddlerscript/modifyrequestorresponse – EricLaw Sep 24 '20 at 20:42
