Description

The Capture ATP Cache are used to store the reply with one of three statuses: "GOOD", "BAD", and "PENDING" from the server.

This cache is looked up before sending a request to the server. A valid "GOOD" or "BAD" entry in the firewall's cache prevents the firewall from generating a request for the same MD5 again. Whereas a "PENDING" entry causes a new request to be sent.
Each cached response also has a lifetime (TTL) that is set by the server when it sends the response. This TTL is can be configured by the server administrator.
When an expired entry is encountered, it is removed from the cache and new request is sent to the server.

The Capture ATP Cache can be cleared by the user by clicking on the "Reset Capture ATP Cache" button on diag.html page.

NOTE: As usual, all operations and settings on diag.html are supposed to be done or changed respectively only with the advice of SonicWall support personnel.
