Also with **X-APISIX-CHAITIN-WAF-ERROR** request header + - waf-err: Error while interacting with the WAF server. Also with **X-APISIX-CHAITIN-WAF-ERROR** request header + - timeout: Timeout for request to the WAF server +- **X-APISIX-CHAITIN-WAF-ERROR**: Debug header. WAF error message +- **X-APISIX-CHAITIN-WAF-TIME**: The time in milliseconds that APISIX spent interacting with WAF. +- **X-APISIX-CHAITIN-WAF-STATUS**: The status code returned to APISIX by the WAF server. +- **X-APISIX-CHAITIN-WAF-ACTION**: Processing result returned to APISIX by the WAF server. + - pass: request valid and passed + - reject: request rejected by WAF service +- **X-APISIX-CHAITIN-WAF-SERVER**: Debug header.
