Dino Espito's article, "Script Callbacks in ASP.NET", in MSDN Magazine provides some information about WebResource.axd (http://msdn.microsoft.com/msdnmag/issues/04/08/CuttingEdge/):

"WebResource.axd is a new built-in HTTP handler in ASP.NET 2.0 that's used to retrieve script code into pages. This handler guarantees that all the script code necessary to perform the callback is correctly referenced within the page or control. In particular, WebResource.axd ensures that calls to WebForm_DoCallback and WebForm_InitCallback are successfully resolved. If you want to take a look at the real source code behind script callbacks in ASP.NET 2.0, open the Temporary Internet Files folder on your Web server machine and look up the file WebResource.axd."

Also see the Microsoft KB article, "Web Events in ASP.NET 2.0" (http://support.microsoft.com/?kbid=893664), about how Web Events publishes information to logs, etc.
