There are several of these scripts out there.....all seem to do exactly what
this does....its certainly good to see other people are still conscious of
it all!

The Atlanta CFUG discussed SQL injection at its last meeting. Here is a
script I wrote for removing all SQL injection from FORM and URL scopes. You
could either put this in a file and including it in your Application.CFM or
turn it into a Function and put it in a CFC and Invoke it from the
Application.CFM. With this done, POOF!!, no SQL Injection! At least not
from the FORM or URL scopes.
Test it here: http://www.dynapp.net/_test.cfm
Let me know if you have any feedback or suggestions.
THANKS!!
Wes
