Hello friends,
If you can GET responses from a SQL database just invoke the ASP page many
times and record the data.
This will work as long as they don't keep connection information e.g. in
their Global.asa file.
If this happens you must be careful to release connections so you don't
overcome their conn limit.
I guess it is a trade-off but you can prove the point to them. Even if you
can get hold of one Uname-Pass that will scare their pants off.
Good Luck.
P.S. It is always nice to see RHBNC graduates Zacharia.
