Wildcards Parent topic

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
