In this case, unfortunately, we are doomed.  William's server push solution
revisits the problem that Internet Explorer doesn't support it.  I too
thought this solution looked interesting so I played around with it a bit
this evening (not knowing my history :).  Unfortunately, Internet Explorer
doesn't support the x-mixed-replace mime type.  It simply renders all
content blocks one after the other, including the boundary string and block
content header.  See for yourself at:
http://perlprogrammer.net/cgi-bin/nph-progressbar.cgi  Sure looks sweet in
some of the other browsers doesn't it?

A quick google on "x-mixed-replace" will show that IE has never supported
server push in this fashion.
