Internet Explorer Extension Development
Where are you trying to access the information from Take a look at www.fiddlertool.com which is a useful tool that already provides this information.
Thanks

The free Fiddler tool is an HTTP proxy that interposes itself between IE and the WinInet system--very low-level stuff. The Dev toolbar does something similar by "simply" hooking the WinInet HttpOpenRequest functions, which is how they can disable images before they appear--by refusing requests.
IEWatch by IEWatch Software does everything you need, in an explorer bar within the IE frame, but be forewarned--it's not free.
PS: Let me also add that hooked functions can easily lead to performance and stability problems in IE, and I do not recommend it as a solution. It is a *warmly* debated topic on the team; extensions that rely on this architecture are vilified to some degree. The fact that it is still being done even by our own tools points to a larger issue that is being addressed over time--namely, what services can IE provide that will make this kind of scenario easier to build and support.
