I am looking for a way to retrieve the HTTP Headers returned on an Image request. I would have thought that this is the meaning of Bug 388518, but as per Christian Biesinger, I am creating a new issue. I would have thought that the correct way to do this would be to return an nsIHttpChannel for an image request, but if you can think of a better way, that would be great. 

I am writing a custom extension that reads headers from the image request.

Reproducible: Always

Steps to Reproduce:
See Bug 388518 for an example that demonstrates the problem.

1.
2.
3.
Actual Results:  
No way to retrieve the nsIHttpChannel interface.

Expected Results:  
Expected to get nsIHttpChannel so that I could call methods on it.

What does firebug do?

I'm closing since this is a 2007 extension feature request that isn't being worked on. If there is still the need for this please re-open.
