* This filter uses "rules" to define the blcking parameters. To configure rules into the configuration file,
* give each rule a unique name and assing the rule contents by passing a string enclosed in quotes.
*
* For example, to block users John and Jane and all users from address range 192.168.0.0/24, the following is needed in the configuration file:
* rule1="block users John Jane"
* rule2="block 192.168.0.0/255.255.255.0"
*
* Rule syntax
*
* [block|allow] [users|columns|times] value ... Blocks or allows the given list of values interpreted as certain type
* require where [all|select|update|insert|delete] ... Requires a where clause for the list of query types
