Web filters usually work in one of two ways: according to category or according to site. These methods work as follows:\n*  According to category: Websites are assigned to categories, for example "Adult", "Gambling", Shopping. When you attempt to connect to a website, the web filtering program checks to which category the website belongs, and whether you have selected to block the category. Downside: obviously, if the website is not assigned a category, or is assigned the wrong category, the filtering won't work.\n*  According to site: When you attempt to connect to a website, the web filtering program checks whether the site is on a black list of specific sites that should be blocked. Downside: if a website is not listed in the black list, it will not be blocked -- and it's impractical to list each and every undesirable website in existence.
