Web Filter, Web Security, and Web Security Gateway (Anywhere), v7.7.x
State Server enables multiple Filtering Service instances to share timing information. This makes it possible to apply time-based filtering actions (like quota time) in deployments that include multiple Filtering Service instances.
Special considerations
*
Install only one State Server instance per logical deployment.
A logical deployment is any group of Policy Server and Filtering Service instances that might handle requests from the same set of users.
*
In a geographically dispersed organization, where each location has its own Policy Server and Filtering Service instances, deploy one State Server instance (on the Policy Server machine or V-Series appliance) at each location.
*
In an organization where all requests are filtered through a central location, only one State Server instance is needed.
*
State Server can be enabled via the Command-Line Utility on full policy source or user identification and filtering appliances.
*
All Filtering Service instances that communicate with the same State Server instance must share the same time zone, and the time on all machines must be in synch.
*
State Server communicates with Filtering Service on port 55828.
*
Each Filtering Service instance can communicate with only one State Server.
*
All Filtering Service instances associated with the same Policy Server must communicate with the same State Server.
*
Multiple Policy Server instances can share a single State Server.
