All Barracuda Web Application Firewalls, all firmware versions
Caching stores commonly used information in local memory for quick retrieval rather than sending frequently used requests to and from the server each time. When a request matching the policy is given to a service, the request is cached. Whenever the same request comes to the service, then the reply is fetched from the cache and given to the user. If cache-status is "off," then the request is directly sent to the server to get the reply.
If specified, HTTP response cache-control headers are ignored for caching decisions. Which means irrespective of what cache-control headers say, we will cache the response.
This option available under Web Sites >> Traffic management >> Caching >> Edit the service and set the value of 'Ignore Response Headers' to NO.
