There was recently a post about this issue. The person
was using IE though, and I believe they fixed it with
a patch.
Alternatively, I tend to send a progress refresh back
to the browser when I have a long running process.
Basically, I start a new thread and run the process in
that. Internally the thread updates a string buffer
with messages that tell the user the status of the
running process. Then I put the thread object in
state. I send a page back to the user trhat contains
the buffer messages plus a refresh tag.
The page comes back and then periodically refreshes
with new data from the message buffer, until the
process completes. Then the complete message buffer is
returned with a completion announcement and no refresh
tag.
