Is it possible to keep some communication going between the browser and web
server going while waiting for a long running process to finish ?

We have one function on our app (ASP.NET / VB.NET) that does a long running
update to the database (takes upto 10 mins) and the browser will often time
out before it completes.

Ideally I'd like to send information back to the browser from the process,
but anything that stops the browser timing out would be good.

Thanks

Steve

Hi Steve,

The other thread is in the same newsgroup and the title is also the same
with this thread. OK, I've repasted my reply there in the bottom for your
convenience. Thanks.

Thanks for Bruce's informative inputs.

Hi Steve,

As Bruce have mentioned, the general meams is to let the long run task
running at serverside( in a background thread ..) and the page response
return as normal. Then, we contantly post back to poll the result from
serverside. And here are some tech article discussing on such topic:
