meta bug for tracking HTTP redirection bugs.

Here is another area to look at.  Several of these top slow loaders 
when compared to other browsers involve being redirected to other sites.   

We need to figure out if any of the dependency bugs on this list
will have impact on improving 'redircted page' loading performance.
    

  Next steps would be to confirm the page loading deltas below, 
  figure out content elements that might be holding 
  us back from doing better on these sites, then translate 
  those problems into bugs with reduced test cases.... 

  Site               - Load Time - Additional Load time over other browsers
  http://www.ANGELFIRE.COM 28.17 27.02
        redirects to http://angelfire.lycos.com/ 
  http://www.abc.com 27.16 25.42
        redirects to http://abc.go.com/ 
  http://www.ITARGET.COM 22.26 20.93
        redirects to http://rewards.mypoints.com/minutes/itarget     
  http://www.YIMG.COM 22.14 20.92
       jrgm finds that yimg.com is a domain used by Yahoo to serve up images. 
There is 
www.yimg.com as far as I know (or can connect to), although you can 
connect to one of their image servers at e.g., http://us.a1.yimg.com 

  http://www.sjmercury.com 21.16 19.87
     redirects to http://www.bayarea.com/ 
  http://www.thecase.com 17.79 16.13
       redirects to http://www.mysterynet.com/club/

chris,

i don't think the remaining depencies listed above could account for the
poor performance numbers.  more likely, it is the fact that we proxy data
from the socket transport thread to the UI thread before HTTP gets a chance
to parse the data.  Some portion of HTTP's processing should really be moved
onto the socket transport thread, so that redirects could be processed more
immediately.  This is a considerable architectural change.

all redirection related bugs taken care of... marking this as fixed.
