[webkit-dev] Using HTTP Auth with XHR

I believe this is a known issue:

<rdar://problem/4335156> XMLHttpRequest ignores username/password  
passed to open()

I need to go ahead and move that radar into bugzilla (or you should  
feel free to file one!), which will make it easier (for someone other  
than me) to fix.

I don't know of any work-arounds.


p.s. Instructions on filing WebKit bugs are available from our  
website: http://www.webkit.org/
