SurfControl Web Filter v5.5

Stand-alone browsing is a single connection to the Internet. For example, stand-alone browsing occurs 
when a user opens their browser and makes a connection to a site, does not go to any subdirectories 
of the site, then either closes their browser or does not make any more connections. 

When a user browses in a stand-alone occurrence, Web Filter calculates the browse time to be equal 
to the Browse Time Sensitivity setting (by default, three minutes). 

A user opens a connection to CNN.com. Technically, they spend forty-five minutes at the site, 
because even though they stop browsing and are working on other tasks, the browser is left open. 

The browse time to CNN.com is calculated to be three minutes because the Browse Time 
Sensitivity is set to three.

Continuous browsing occurs when there is a sequence of connections, each one made within three 
minutes of the last. SurfControl Web Filter automatically adds the browse time sensitivity value to the 
last connection in the sequence.

A user opens their browser and makes a connection to ebay.com for two minutes, connects to 
ebay.com\ebaymotors for one minute, then opens ebay.com\ebaymotors\motorcycles for one 
minute. Web Filter records the browse time as in the table below:
