    G'day All!


    I receive a Chrome error about missing the above header.


    When I have Fiddler running, this header is added, and the website works fine.

    Only problem is I can't see what is going on with the web requests, as everything works with Fiddler running.


    How do I stop Fiddler adding the Access-Control-Allow-Origin header?

    Sorry about the delayed response.

    Are you sure Fiddler adds this header to the response? The server might be sending this header back when Fiddler makes the request.

    Here's how you can view and modify the response and request -

    G'day Tsviatko!


    Pretty sure. The 'usual' works as I expected on another machine applied.

    I had somehow ticked on Rules -> Automatically Authenticate and that added the extra header.

    Turning that off (which is the default) let me see what I needed to see.
