How to process data AFTER page is completely loaded for the user?

Posted By:      Posted Date: August 24, 2010    Points: 0   Category :ASP.Net

I have some logging that has to be done, which are some database update or inserts.

However this logging is of no importance to the user, so I only want to process the data/logs after the page is completed for the user.

So I want this code only executed after that the page is complete.

I've been checking out Ajax, async pages etc, but the problem is it still gets executed before the page is rendered to the client, which means the client will have to wait longer then it is not being processed.

I've been checking out Threadpool.queueBackgroundWorker, however if I get it correct, this will still be executed before the page is shown to the user, as it has to complete before the prerender.

Then I thought about creating a new thread, and do the processing there, which would not have my page waiting to complete the data/logging.
However when I have 100 or 200 users loading pages at the same time, then that would mean I would be creating 200 threads on those loads, which I doubt will be good for performance. So if I want to solve this, I would have to create my own threadpool and only assign for example a max of 40 threads to it which can pr
