web chat development, http header connection: keep-alive

[Luiz Alberto Gibson da Costa]

Hi,
I'm developing a web chat in asp.net that is composed of two frames.
The top frame shows the messages and the bottom one allows the user to
post messages. The problem is that the browser tries to download both
frames using a single connection (http header "connection:
keep-alive"). The bottom frame is never downloaded then because the
browser never finishes downloading the top frame.
Any suggestions?

Thanks,
Luiz
