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
Now launch Visual Policy Manager and add a new Web Access Layer.
Right click on Action and select Set.
Click on New… and select Volume Quota…
In the new window, configure the settings as required.
a) Quota Period
b) Amount to be allowed
c) Show warning when crossing a certain percentage of usage (optional)
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.

Volume Quota will be only applicable for data which ProxySG can see. i.e. If SSL Interception is not enabled, any data communicated over the SSL tunnel will not be seen by Proxy. Data without interception will not be added to users Quota. For effective control on Volume Quota control, SSL interception is needed.
