[GitHub] [apisix] exotfboy opened a new issue, #7709: help request: Host is not rewritten
exotfboy opened a new issue, #7709:
URL: https://github.com/apache/apisix/issues/7709
### Description
I tried to test APISIX by using `httpbin` as a back-end service. For client request `http://localhost:9080/get?type=six`, what I got:
```
{
"args": {
"type": "six"
},
"headers": {
"Accept": "text/html,application/xhtml+xml,application/xml;q=0.9,image/avif,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9",

"Sec-Fetch-Dest": "document",
"Sec-Fetch-Mode": "navigate",
"Sec-Fetch-Site": "none",
"Sec-Fetch-User": "?1",

"User-Agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/104.0.5112.79 Safari/537.36",
"X-Amzn-Trace-Id": "Root=1-62fc4e4d-05c9f7de59712888753f8e41",
"X-Forwarded-Host": "localhost"
},
"origin": "172.20.0.1, xxx.xxx.xxx.xxx",
"url": "http://localhost/get?type=six"
}
```
Note that the response url is `http://localhost/get?type=six` which is not exactly the same as the request. Is this expected?
### Environment
- APISIX version (run `apisix version`): `2.15.0`
- Operating system (run `uname -a`): `Linux pc 5.4.0-84-generic #94~18.04.1-Ubuntu`
- etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`):`34.0`
- APISIX Dashboard version, if relevant: `2.13.0`

This is because the `X-Forwarded-Host` passed by `Traefik` is `localhost:88` While it's `localhost` in Apache APISIX .

@tokers Thanks for your attention. And it is clear now:
Traefik send both the origin host and port in `X-Forwarded-Host`.
APISIX send the `host` by `X-Forwarded-Host` and `port` by `X-Forwarded-Port` to the backend while httpbin ignore the port.
So the problem is should the `X-Forwarded-Host` contain the `port` part. I think so. As the MDN said in https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Host
> The `Host` request header specifies the host and port number of the server to which the request is being sent.

@tzssangglass `80` is the default web port or you can think `httpbin.org:80`/get is the same as `httpbin.org/get`. But in my example, the request and response url are two absolutely different url.

see:
```
curl http://httpbin.org:80/get
{
"args": {},
"headers": {
"Accept": "*/*",
"Host": "httpbin.org",
"User-Agent": "curl/7.84.0",
"X-Amzn-Trace-Id": "Root=1-62fc608f-7400b47e0df9164813ce5689"
},
"origin": "xxxxx",
"url": "http://httpbin.org/get"
}
```
the port `80` is ignored by httpbin.

@exotfboy Try to find documents about how httpbin concates the `url`.

Actually, Apache APISIX will also add the `X-Forwarded-Port` header, but it's not shown by HTTPBIN, I guess it was concealed by AWS.

I tried `traefid` too, and get the desired result:
Maybe this has nothing to do with how httpbin concating the `url` but how the api gateway forward the request.
