I'm not entirely sure this is a bug or a design decision, but I could not find any information on this in bugzilla or via google.

I've noticed when surfing Google and it prefetches a site, that it will send the 'X-moz: prefetch' header. However, if the url it fetches is a redirect it does not include this 'X-moz' header when accessing the redirect page.

Reproducible: Always

Steps to Reproduce:
You should be able to just setup a prefetched link in some html that points to a url that redirects to another page. On the second access in the prefetch process you will see that 'X-moz: prefetch' is not included in the header.
Something like:
<link rel="prefetch" href="">
and let's say redirects to:
Actual Results:  
No X-moz header sent for mypage.html.

Expected Results:  
I think the X-moz header might need to be there.

Simple patch.  I also noticed that nsPrefetchService::mCurrentChannel is not updated when we process a redirect.  I think it should be updated since nsPrefetchService::StopProcessing calls Cancel on mCurrentChannel.

+    // HTTP request headers are not automatically forwarded to the new channel.

maybe there should be a way to do that though... but ok, r=biesi
