Blue Coat introduced a new feature in SGOS 6.6.x called Volume Quota. With this feature, you can control the amount of data a user can receive during a period of time. This can be set for time period of Hourly, Daily or Weekly.
This can be used to control how much data a user gets through ProxySG.
For using quota feature, ProxySG SGOS version needs to be a minimum of 6.6.x.
Before creating the policy, quota feature needs to be enabled by executing below command.
#(config) policy quota
Sample configuration below
Above configuration is set to allow a user to receive only 50MB of data within a period of 1 hour. When the usage reaches 80% of the above set value (i.e. 40MB in this case), he will be issued a warning. After 1 hour the quota will get reset and user can continue to receive more data.
