zuiyangqingzhou opened a new issue, #7258: URL: https://github.com/apache/apisix/issues/7258
### Current Behavior currently, apisix gets the "X-Forwarded-Proto" header when calling the set_upstream_headers function, https://github.com/apache/apisix/blob/master/apisix/init.lua#L228-L239 but it reads all the headers first, which may cause the CPU to rise abnormally if the number of headers is very large and the size is large https://github.com/apache/apisix/blob/master/apisix/core/request.lua#L45-L66 <img width="1888" alt="image" src="https://user-images.githubusercontent.com/17425270/173836187-b2680e9f-9d34-45af-865e-7f03ca585790.png";> ### Expected Behavior _No response_ ### Error Logs _No response_ ### Steps to Reproduce none ### Environment - APISIX version (run `apisix version`): - Operating system (run `uname -a`): - OpenResty / Nginx version (run `openresty -V` or `nginx -V`): - etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`): - APISIX Dashboard version, if relevant: - Plugin runner version, for issues related to plugin runners: - LuaRocks version, for installation issues (run `luarocks --version`): -- This is an automated message from the Apache Git Service.
