developing better wait page.

These days i worked till late night. Doing some CSV datamining project for windows CE & for ASP.net. In ASP.net site basically doing some csv data synchornization. But its takes while to copy bunch of data to the database server. And the page didnt render until job done. So i just planned to have a wait page so that user will get notified abt the process going on in different thread. I found a cool article in ASP.NET site which helped me to overcome the problem. You get a better idea abt it.
