wls981 opened a new issue, #4276: URL: https://github.com/apache/shenyu/issues/4276
### Is there an existing issue for this? - [X] I have searched the existing issues ### Current Behavior    As shown in the picture above, after being proxied by the divide plug-in, the cookie in the returned HTTP response header is repeated. shenyu 2.4.3 and 2.5.0 can be reproduced. ### Expected Behavior The cookie should not be repeated, because I find that after an http url passes through the gateway, the <Transfer-Encoding: chunked> header in the response header is also repeated, which causes the nginx in front of the gateway to report an error. ### Steps To Reproduce Download shenyu-2.5.0-bootstrap-bin.tar.gz and shenyu-2.5.0-admin-bin.tar.gz directly from the official website, and simply configure the divide plug-in code to reproduce. ### Environment ```markdown ShenYu version(s):2.4.3 、 2.5.0 ``` ### Debug logs none ### Anything else? _No response_ -- This is an automated message from the Apache Git Service.
