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

[Sportmodus]

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.
