Billion Electric Company 7300VP - Manual (Page 68)

Active: Select Yes from the drop down list box to enable or disable the URL Filter
feature.
Always Block: Select to always check URL filter rules (i.e. at all hours of the day).
Block from: Specify the time period to check URL filter rules (e.g. during work hours).
Keywords Filtering: Allows blocking by specific keywords within a particular URL
rather than having to specify a complete URL (e.g. to block any image called
“advertisement.gif”). When enabled, your specified keywords list is checked to see if any
keywords are present in URLs accessed to determine if the connection attempt should be
blocked. Note that the URL filter blocks web browser (HTTP) connection attempts using
port 80 only.
For example, the URL http://www.abc.com/abcde.html would be dropped since the keyword
“abcde” occurs in the URL.
