zhendongcmss opened a new issue, #9585:
URL: https://github.com/apache/apisix/issues/9585
### Current Behavior
- I want close the connection on header_filter_by_lua phase, I add the code
on `apisix/plugins/response-rewrite.lua` to test it.
```
function _M.header_filter(conf, ctx)
if true then
ngx.header.connection = "close"
ngx.status = 444
ngx.exit(444)
return
end
...
```
- Test it, the connection was closed.
```
curl 127.0.0.1:9080/test/ -i
curl: (52) Empty reply from server
```
- But I got error
error.log
```

- The lua-nginx-module say ngx.exit() can be used on header_filter_by_lua.
https://github.com/openresty/lua-nginx-module#ngxexit
syntax: ngx.exit(status)
context: rewrite_by_lua*, access_by_lua*, content_by_lua*,
header_filter_by_lua*, ngx.timer.*, balancer_by_lua*, ssl_certificate_by_lua*,
ssl_session_fetch_by_lua*, ssl_session_store_by_lua*, ssl_client_hello_by_lua*
- I try on 2.10.1 and master branch both have this issue.
