I hate to be so web 1.0 but perhaps using iframe tags for now to load
the ad's until the ajax problem is solved? My assumption was that ajax
was always asyncronous.. hence the Asyncronus JAvasctipt Xml
anacronism (have I got that right?). Didn't know you can do it
syncronously as well.
Is that something you perhaps set up in XMLHttpRequest object? Maybe
Jquery can give you access to the request object and you can set
fields that way.
Taking a stab in the dark,
