Gary Ranne here from the IE Team with a quick tip on how to use Fiddler to identify codebase objects on a webpage.
With the inception of the ActiveX installer service it is even more important to be aware of the location that ActiveX controls are being installed from. Frequently, this can be done simply by viewing the source of the Web page that is loading the control. All we need to do is to look for an Object tag that contains a “codebase” attribute. This “codebase” attribute points to the location that the control will be downloaded from. This works great when the Object is being loaded from the page itself, but it is not uncommon for a control to be loaded from a .js file or a .css file. How can we locate the codebase in these cercumstances?
