### Description The `ai-proxy` and `ai-proxy-multi` plugins forward the incoming client request headers to the configured LLM upstream by default, dropping only `Host`, `Content-Length`, and `Accept-Encoding` and forcing `Content-Type` to `application/json`. This behavior is not currently described in the plugin documentation. This PR documents the behavior in a new "Request Header Forwarding" section for both plugins (English and Chinese docs). It explains: - which headers are dropped and which are forced; - that headers configured under `auth.header` take precedence over client headers of the same name; - that, since the LLM upstream is often a third-party service, operators should strip headers they do not want to expose (for example `Authorization` or `Cookie`) before the request reaches the plugin, e.g. with `proxy-rewrite`. Documentation only. No code or behavior changes. #### Which issue(s) this PR fixes: Fixes # ### Checklist - [x] I have explained the need for this PR and the problem it solves - [x] I have explained the changes or the new features added to this PR - [ ] I have added tests corresponding to this change - [x] I have updated the documentation to reflect this change - [x] I have verified that this change is backward compatible (If not, please discuss on the [APISIX mailing list](https://github.com/apache/apisix/tree/master#community) first) -- This is an automated message from the Apache Git Service.
