About Browse Time Sensitivity
Browse time sensitivity refers to the maximum amount of time Web Filter presumes a user to be actively
engaged with a site. Browse time sensitivity is also used to offset the uncertainty about how much actual
time a user is engaged in browsing. By default, browse time sensitivity is set to three minutes.
Browse time sensitivity comes into play every time a user launches a browser. However, the way in which
Web Filter attributes browse time sensitivity depends on whether the browsing takes place as a stand-
alone occurrence or in a sequence of connections.
Note: If the first file a user attempts to download exceeds the volume limit, this file will still be
downloaded. All subsequent download attempts will be blocked. Web Filter can only judge the
size of a file once it has been downloaded.
