Description

Hi, the code below:

stream {

server {

listen 80;
proxy_pass $host:80;

}

}
How could I get the host param in stream server if incoming a http request?

Is there any possible to get the http host param, just like the $host in ngx_http_core_module?

Thanks!

There are no plans to implement something like this. If for some reason you need to detect HTTP requests in the stream module and handle them specially depending on the headers, you can try writing appropriate detection code using njs, see #1951 for an example. Note though that something like this is usually a bad idea, since the same connection can be used for multiple requests to different hosts (not to mention it might be non-trivial to correctly extract Host from an HTTP request). If you want to proxy HTTP requests, consider using the HTTP module instead.

Note: See TracTickets for help on using tickets.
