If the user clicks Continue,Websense Express permits the site, and the page is displayed until the browseris closed or another site is requested.Clicking Continue starts a timer. During the configured time period (60seconds by default), the user can visit other sites in Continue categorieswithout encountering another block page. To change the default time period,go to Server > Settings > Common Filtering and edit the Continue timeoutfield.Once the time period ends, browsing to another Continue site results in aContinue block page.Implementing keyword blockingKeywords offer protection against sites that have not been explicitly added tothe Master Database or a custom URLs list. Keywords can be associated withany URL category, including custom categories.When the Block Keyword setting is active for a category, Websense softwareblocks any site whose URL contains an associated keyword, even if the sitefalls into another URL category.For example, if keyword blocking is applied to the Sports category, and thekeyword “nba” is associated with Sports, the URL sports.espn.go.com/nba/30 Websense, Inc.
