Wildcards

IWSVA supports both the * (string) and ? (character) wildcards in Match: field for URL Blocking, URL Filtering, and Trusted URLs. Wildcards are also supported in both the Approved and Block lists.

• For approved filename lists, IWSVA supports only the * wildcard.

Using Wildcards

To represent one or more unknown characters, follow these guidelines:

• ?lock—matches: block, clock, glock, plock, and flock (but not lock)

• Trend?Micro—matches: Trend Micro, Trend-Micro, Trend_Micro (but not TrendMicro)

• block*—matches: blocking, blocked, blocker, blocks, blockhead, block-point, (but not block)

Using ? or * not as a wildcard

To represent an asterisk (or star) or a question mark, use the following:

• specify the html  code %2a to display an asterisk: *

• specify the html code %3f to display question mark: ?

For example,

• to block http://www.*power.com, write the rule like this: http://www.%2apower.com

• To block http://www.you_rang?.com, write the rule like this: http://www.you_rang%3f.com
