Double url-encodes all characters in a given payload (not processing

already encoded)
|
|
|
|
Example:
|
|
* Input: SELECT FIELD FROM%20TABLE
|
|
* Output: %2553%2545%254c%2545%2543%2554%2520%2546%2549%2545%254c%2544%2520%2546%2552%254f%254d%2520%2554%2541%2542%254c%2545

Notes:
|
|
* Useful to bypass some weak web application firewalls that do not
|
|
double url-decode the request before processing it through their

ruleset
