### Is there an existing issue for this? - [X] I have searched the existing issues ### Current Behavior 1. The access to the system using the network segment 192.168.40 is blocked, as expected 2. The network segment 192.168.42 is used to access the system. The forwarding is normal and meets expectations 3. The network segment 192.168.40 is used to access the system, and the forwarding is normal Cause of the problem: 1. When network segment 192.168.42 accesses the system and no rule is matched, an empty rule is added to the MatchDataCache.RULE_DATA_MAP cache 3. When the 192.168.40 network segment is used again, the null rule is obtained from the MatchDataCache.RULE_DATA_MAP cache, and the actual rule does not take effect Temporary solutions: 1. Modify defaultMatchRule in AbstractShenyuPlugin to write the empty rule rule to cached code comments   ### Expected Behavior _No response_ ### Steps To Reproduce _No response_ ### Environment ```markdown ShenYu version(s):2.6.0 ``` ### Debug logs _No response_ ### Anything else? _No response_ -- This is an automated message from the Apache Git Service.
