"""

Url-encodes all characters in a given payload (not processing already

encoded)

Tested against:

* Microsoft SQL Server 2005

* MySQL 4, 5.0 and 5.5

* Oracle 10g

* PostgreSQL 8.3, 8.4, 9.0

Notes:

* Useful to bypass very weak web application firewalls that do not

url-decode the request before processing it through their ruleset

* The web server will anyway pass the url-decoded version behind,

hence it should work against any DBMS
