FAQ's for Cloud WAF Rules

|Q. Is there a way to setup shared Rules that can be enabled for multiple sites without having to create separate rules that do the same thing for multiple websites?
|A. The framework has been created and available now to apply policy for SiteACL and whitelist to sub-account and sites. Incaprule is planned to added in this framework. As of now incaprules are not part of policy framework so these need to be manually copied or use API to copy them between sites.

|Q. Can we pass the client_IP value in the header rewrite?    
|A. By default the client_ip is sent in XFF and incap_client_ip header to origin . A custom rule is not available yet. 

|Q.  If we have configured cache on the WAF, deploying new rules are they applied immediately? Usually comments are configured on static pages, and hence we do add cache on static pages, adding rules, will it be applied immediately?(Limit number of comments)
|A. Cache policies can detect possible dynamic content by learning or custom rules can help, but the incaprules are applied within few seconds across the CDN. Not sure what is the actual ask here 6. Is their a possibility to setup a rule to block udp flooding? WAF by default have DDOS protection and UDP flooding never reach origin as CWAF will pass only web traffic to origin. If the origin is non web application Infra and per IP DDOS solutions are also available
