Fiddler FAQ

Headers, How to add headers

1. Run fiddler
2. Use the editor
3. Find the method:    static function OnBeforeRequest(oSession: Session) {
4. At the end of it add your handler code.
5. Save the changes and try it (seems like fiddler picks up the changes when you save)
6. See the sample here:

        if (oSession.fullUrl.Contains("/somepartOfUrlToMatch"))

        {

            FiddlerObject.alert('show alert');

            oSession.oRequest["X-MY-USER"]="someUsername";

            oSession.oRequest["X-MY-ROLE"]="someRole";

        }

Installing it:

1. Get it from telrick http://www.telerik.com/fiddler
2. Install it.
3. Run it
4. Try to "Rules -> Customize Rules" and then have it download the editor for you (or if you are a masochist edit in the default editor)
5. Install the editor
6. Use the editor to adjust the rules (it seems to automatically know where the file is and to automatically load it)

Popup, How to show a debug popup:
FiddlerObject.alert('show this message');
