Sample RAS script for ASP:

The following script was contributed by Aaron Alexander of  Apparently Aaron spent a lot of time with Business Objects Developer Support team getting the RAS code to work.  (It isn't very well documented.)  After several significant contributions from the guys at BO, Aaron came up with the following generic script that he thought would benefit others.   He says that it has been working, trouble free, for several months.   It comes with no guarantees, but you can use it however you like.  Please let me know if you have any feedback.
