deekshith-hadil opened a new issue, #12721:
URL: https://github.com/apache/apisix/issues/12721
### Description
I have a scenario where APISIX acts as the primary proxy for most users.
However, in certain cases, some users access our services via a second proxy,
which then forwards the request to APISIX. The architecture is illustrated
below:
```mermaid
flowchart LR
subgraph User Side
User1["User"]
User2["User (via 2nd Proxy)"]
end
subgraph Front Proxy
FrontProxy["Proxy #2"]
end
subgraph APISIX Layer
APISIX["APISIX (Proxy)"]
end
subgraph Backend
HTTPPod["HTTP Pod"]
end
User1 -- HTTP Request --> APISIX
User2 -- HTTP Request --> FrontProxy
FrontProxy -- Forwards Request --> APISIX
APISIX -- Proxies Request --> HTTPPod
```
**Problem:**
When a request comes via Proxy #2, I want APISIX to identify and set the
`X-Forwarded-Host` and `X-Forwarded-Port` headers to the values from Proxy #2,
rather than its own (APISIX pod) host and port.
I understand that a custom plugin could potentially achieve this, but so
far, APISIX does **not** override `X-Forwarded-Host` and `X-Forwarded-Port` as
expected—it continues to set them to APISIX's own host and port.
### What I've Tried
- **proxy-rewrite plugin**
- **serverless-pre-function plugin**
- **serverless-post-function plugin**
I've followed the discussions and suggestions in the threads below, but none
of these solutions have worked for me:
- [apache/apisix/issues/11974](https://github.com/apache/apisix/issues/11974)
- [apache/apisix/pull/8226](https://github.com/apache/apisix/pull/8226)
- [apache/apisix/issues/9530](https://github.com/apache/apisix/issues/9530)

- [apache/apisix/issues/11580](https://github.com/apache/apisix/issues/11580)

**Questions:**
- Is there a recommended way to have APISIX set or override
`X-Forwarded-Host` and `X-Forwarded-Port` when requests are forwarded by
another proxy?
- Is this currently supported by APISIX, or is it a known limitation?
- Are there any workarounds or plugins I might have missed?
Any guidance or suggestions would be greatly appreciated!
### 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`):
