sundialsvc4 has beaten me to it, but worth reinforcing the concept.

Browsers are inherently an interactive medium: you request something, you get something, repeat as necessary. Well you can stretch the concept a little but sometimes things just don't fit that pattern. In that case it's better to forget about delivering a request synchronously, and just turn it into a queued request.

As Occam said: Entia non sunt multiplicanda praeter necessitatem.
