Main idea

    IISTracer monitors all communication between IIS server and client browser. It works with client request during process headers, authentication, read/write data and end of request. ISAPI filter has an ability to stop request in each of these request states.

    The request is stopped when IIS calls next ISAPI filter notification on this request - usually read/write raw data. This functionality lets you stop 'living' requests, requests with living communication between client browser and IIS - usually large uploads/downloads, real-time data communication ASP scripts (without buffering), etc.

    Note: ASP pages (and other scripts) are usually running as buffered and does not communicate with client until they are finished. So if you request to stop such ASP script in 'authentication' state, the request is finished in send response event.
