'corp-domain.com', 'other-domain.com', ), 'deny' => array( 'blocked-domain.com', 'other-blocked-domain.com', ), )  The keys 'whitelist' and 'blacklist' may also be used for 'allow' and 'deny', respectively.  An 'allow' or 'deny' value that is a string is converted to a single element array.  Wildcard matching may be used on domain names: the prefix '*.' means match any domain that ends with the given suffix. A '*' component can also be used inside the hostname, and will match zero or more domain name components.  If the 'allow' list is empty or unset, the default behavior is to accept ALL domains other than those listed in the 'deny' list.  If the 'deny' list is empty or unset, the default behavior is to deny ALL domains other than those listed in the 'allow' list.  If both 'allow' and 'deny' lists are provided, the default behavior is to accept a domain name that does not match any of the patterns provided. The 'allow' list is checked first, followed by 'deny'. To obtain the opposite behavior, specify the wildcard '*' as the last entry in the 'deny' list.  IsValidFileUpload - Checks that the value is a file upload.  IsValidFutureDateTime - Checks that the value is a valid time specification string according to the rules of the PHP function strtotime(), and that the time specification refers to a point in the future.  IsValidFutureTimestamp - Checks that the value is a valid UNIX time referring to a point in the future.  IsValidHostname - Checks that the value is a valid IP address or a hostname that resolves to an IP address.  IsValidHostnameCidr - Checks that the value is a valid IP address or hostname, which may also have an optional /N suffix indicating the network prefix length in bits (CIDR notation).  IsValidHostnamePort - Checks that the value is a valid IP address or hostname, which may optionally include a port number specified with the syntax hostname:port.  IsValidIpAddr - Checks that the value is a valid IP address.  IsValidLdapAttribute - Checks that the value is a valid LDAP attribute name; that is, a string that starts with a letter, and which contains only letters, numbers, underscore (_) and hyphen (-).  IsValidNetmask - Checks that the value is a valid network mask in dotted-quad notation; that is, an IP address such as 255.255.255.128 that contains a single string of N 1 bits followed by (32 - N) 0 bits.  IsValidNumber - Checks that the value is numeric; that is, an integer or a decimal value. The validator argument may be an array containing one or more of the following additional options:  no_negative - if set to true, negative numbers are not accepted as a valid value.  no_zero - if set to true, zero is not accepted as a valid value.  only_integer - if set to true, decimal numbers are not accepted and only integer values are valid.  IsValidPassword2 - Checks that the value is a valid password that satisfies certain requirements. The validator argument must be an array describing which of the following requirements to check. To perform any password checking, the "minimum_length" and "complexity_mode" fields must be specified.  password2 - specifies the name of the field containing the duplicate password entry (optional, for password validation). Defaults to "password2" if not specified.  password2_required - if nonzero, indicates that the "password2" entry must be supplied. 396 | Reference Amigopod 3.7 | Deployment Guide
