Volume Quota

By configuring volume quotas, you can limit the volume of web objects, measured in GB and MB, that the users
of your network are allowed to download from the web.
Volume quotas can be related to several parameters:

  • URL categories — Users are allowed to download only a limited volume of web objects through URLs that fall into particular categories, for example, Streaming Media.
  • IP addresses — Users who send download requests from particular IP addresses are allowed only a limited volume.
  • User names — Users are allowed to download web objects only up to a limited volume. Users are identified by the user names they submitted for authentication on the appliance.
  • Media types — Users are allowed to download web objects belonging to particular media types only up to a limited volume.

These parameters are used by the rules in the library rule set for volume quotas. You can create rules of your own that use other parameters in relation to volume quotas.

Information on the volume that users download from the web is stored on the appliance. When the configured volume quota has been exceeded for a user, a request that this user sends is blocked. A message is displayed to the user stating why the request was blocked.

Users are identified by the user names they submitted for authentication. If no user name is sent with a request, web usage is recorded and blocked or allowed for the IP address of the client system that the request was sent from. 

Web downloads can be limited to volume downloaded per day, per week, or per month.
