About Request Analytics

A Request Analytics item inspects an outgoing web request for malicious embedded contents. In a per-request policy, a Request Analytics item must be preceded by a Category Lookup item and followed by a URL Filter Assign item. To block outgoing traffic from chat applications, a Request Analytics item is required.
Request Analytics works only on a BIG-IP® system with an SWG subscription.
Request Analytics provides these elements and options.
Max Buffer Size
Specifies the maximum amount of request data (in bytes) to collect before sending it for content scanning. The system sends the content for analysis when the buffer reaches this size or when the buffer contains all of the request content. Otherwise, the system retains the request data in the buffer.
Max Buffer Time
Specifies the maximum amount of time (in seconds) for buffering and analyzing request data. If the time elapses at any point in this process, the agent sets the
perflow.request_analytics.failure
variable to 1 (which indicates an ANTserver failure) and discards the request data.
Reset on Failure
When enabled, specifies that SWG send a TCP reset to the client in the event of an ANTserver failure. If disabled and an ANTserver failure occurs, SWG logs all perflow variables and provides the SWG block page to the client.
