 XSS Filtering
 *************
 
-CodeIgniter comes with a Cross Site Scripting Hack prevention filter
-which can either run automatically to filter all POST and COOKIE data
-that is encountered, or you can run it on a per item basis. By default
-it does **not** run globally since it requires a bit of processing
-overhead, and since you may not need it in all cases.
-
-The XSS filter looks for commonly used techniques to trigger Javascript
-or other types of code that attempt to hijack cookies or do other
-malicious things. If anything disallowed is encountered it is rendered
-safe by converting the data to character entities.
