NGINX: Set/use requests with fully qualified domain name (= FQDN)

Hi @ all. NGINX proxy_pass works great with our internal servers. Thanks
for
the good work.

Now I want to proxy_pass an external server and I have to use our proxy
for
this to get an external connection.

I checked with tcpdump and Wireshark. NGINX sends

“GET /uri HTTP/1.1
HOST: external.com

to my upstream (= coporate proxy).

Can I modify this to

“GET http://external.com:80/uri HTTP/1.1
HOST: external.com

?

Problem is: Our proxy denies requests (error 400 bad request) without
FQDN
(= fully qualified domain name).

Any help or workaround is welcome.

Stock nginx does not speak proxy-http to a proxy server.

Only if you arrange for the code to do it be written.

If you choose to write it fully, it might be welcomed into stock nginx.

Your proxy is correct to do so.

It just expects a protocol that nginx does not speak.

Any help or workaround is welcome.

Use something that can be a proxy client, and use it instead of (or as
well as) nginx.

Or, since nginx is a reverse proxy, and you only reverse proxy for
things
you control, change your policy so that nginx can talk to your external
web server without going through the proxy.

I don’t think that there is a “good” answer.

Thanks.

I used Apache (behind NGINX) with

ProxyRemote * http://proxy:8080

in conjunction with ProxyPass. Works!
