🐛 subdomain multiplexing on 1 connection bugs out some webservers with keep-alive

**Describe the bug**
Using different subdomains pointing to the same service will multiplex the requests over 1 connection. This bugs out certain webservers + caching mechanisms.

**To Reproduce**
```
config="{"ingress":[
{"hostname":"myservice.mysite.ai", "service":"http://localhost:80"},
{"hostname":"*.myservice.mysite.ai", "originRequest":{}, "service":"http://localhost:80"}
]
```

When we visit `123.myservice.mysite.ai` we get what is hosted on `123` and connection is keep-alive. If we visit now `abc.myservice.mysite.ai` the request goes over the same keep-alive connection that hit `123.myservice.mysite.ai`, a new connection is not created.

This behavior is not present using CloudFlare proxy (2 seperate connections are created), this is solely an issue when tunnel is used.

**Expected behavior**
A separate connection should be opened when the host changes.

**Environment and versions**
