How to use IHTTPAsyncHandler?

Question

Imagine I have some code to read from the start to end of a file like so:

while(sw.readline != null) {

}

I want this to be fully asynchronous. When deriving from IHTTPAsyncHandler, where would this code go and where would would the code to get the content of each line go? I'm a little confused of how to use this interface as I haven't seen a good example on the net.

Thanks

I recently added some asynchronous processes to my ASP.NET pages in order to allow some long-running processes to take place while the user waited for the results. I found the IHTTPAsyncHandler quite inadequate. All it does is allow you to spin off a new thread while the page begins processing. You still have to make your own thread and create a AsyncRequestResult.

Instead I ended up just using a normal thread in my codebehind instead, much more succinct:

Thread thread = new Thread(new ThreadStart(myAsyncProcess));
thread.Start();
...
private void myAsyncProcess() {
   // Long running process
}
