### Description `core.request.headers()` reads request headers with `ngx.req.get_headers()`, which returns the first 100 headers by default. So `request-validation` checks `header_schema` against those 100 headers, and `opa` sends only those 100 in `request.headers`. Headers after the 100th are still forwarded to the Upstream. This PR documents that limit in the `request-validation` and `opa` plugin docs (English and Chinese) and points to `proxy-rewrite`'s `headers.remove` for keeping a header from reaching the Upstream. #### 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.
