Question

I use a 1×1 image tag to implement tracking on my website. The src attribute of the image tag is a call to a custom asp.net handler that I’ve written.

This handler inserts some data to the database. It gets millions of hits a day so I need the database insert to be async.

I’ve never done multithreaded programming so am seeking some assistance on how to go about this.

My handler should invoke a new thread which inserts data to the database and immediately return the 1×1 image to the client.

If the database insert is slow, the handler should not wait till it is finished but immediately return the image to the client.

Thanks
