In an asp.net application, we'd like to use the SqlWebEventProvider to log any Event that occurs during the application lifetime.

The problem is that we think that the table aspnet_WebEvent_Event doesn't provide enough columns and should log more information (we need to keep the Logged user).
I'm aware that this information could be stored in the "Details" column but it wouldn't then be really simple to filter the results and build reports.

So I'm searching for a simple solution to add a column. I wish I could derive SqlWebEventProvider but the methods used to build the stocked procedure parameters are private (PrepareParams() and FillParams()).

Any simple solution that doesn't imply to rewrite the entire Provider class ?
