How do I ignore HTTP response cache-control headers on Barracuda Web Application Firewall for caching decisions?

Scope:
All Barracuda Web Application Firewalls, all firmware versions
 
Answer:
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.
