Sn0rt opened a new issue, #10366: URL: https://github.com/apache/apisix/issues/10366
### Current Behavior When http traffic carries the `Content-Type: application/x-www-form-urlencoded;charset=UTF-8` header, post_arg cannot correctly distribute grayscale traffic. Using `Content-Type: application/x-www-form-urlencoded` as the http header traffic-split can distribute the traffic normally. ### Expected Behavior When http traffic carries `Content-Type: application/x-www-form-urlencoded;charset=UTF-8` and `Content-Type: application/x-www-form-urlencoded` headers, both grayscale traffic can be matched normally. . ### Error Logs N/A ### Steps to Reproduce ```lua # # Licensed to the Apache Software Foundation (ASF) under one or more # contributor license agreements.
