        if (oSession.uriContains("google.com")) {
            FiddlerApplication.Log.LogString("before "+oSession.GetResponseBodyAsString());
            oSession.utilSetResponseBody("empty");

hi.

i am trying to chage response body from third party website.

in fiddler log i see that response body is changed, but browser receives unchanged response body.

can anybody to help me with my issue?

In 99% of the cases where someone reports this issue it turns out that they've configured the response body to stream to the client as it is read from the server (e.g. by pushing the STREAM button in Fiddler's toolbar). When that happens, the client is fed the blocks of the response as it is downloaded, and the event handler mentioned only executes after the response has already been returned.

If you disable Streaming, it should work as you expect.

Hi,

For browsers like IE and Chrome to trust Fiddler's root certificate, you must accept the prompt that is shown when you first enable HTTPS decryption inside Fiddler.

For Firefox, which does not respect the Windows Certificate store, you must manually trust Fiddler's root certificate: http://www.telerik.com/blogs/configuring-firefox-for-fiddler

Hi,

Have you tried to use the AutoResponder feature of Fiddler?

In this blogpost you can find how to use it to change the response to the client. Can you give it a try and see if this is what you're looking for?
