frames, location.href, loading

[Mark Gibson]

I have a page made up of 3 frames. Say I have a function:

function changeLocation(url)
{
top.topnav.location.href=url + '/top' ;
top.body.location.href=url + '/body' ;
top.leftnav.location.href=url + '/leftnav' ;
}

I believe that these pages get loaded synchronously. First,
top.topnav is loaded - When it completes, top.body is loaded,
when it completes, top.leftnav is loaded.

Is there a way to instruct the browser to start loading top.topnav,
then immediately start loading top.body, then top.leftnav?

In other words, I don't want to wait until url + '/top' is
loaded for top.topnav the server before I request url+'/body'
for top.body.

Does this make any sense?
