ASP.NET Web Applications ASP.NET Trace Functionality
Whether you choose to view trace information appended at the end of an ASP.NET page or by using the trace application, the information displayed is the same. ASP.NET organizes the trace information in a series of tables that details specifics about the page request that you are viewing, all trace information, including any trace messages you have written, for the request, the control hierarchy for the page, and a series of tables detailing the Cookies, Headers, and Form collection information for the request, as well as information about the server variables associated with the request.
Trace information appears in the following order once you have enabled tracing for a page or application.
