- -I is not a proxy address, it's the web server address to connect to. -u
should be only the path component of the url ("/", "/foo/bar.html",
etc.). -H can be used together with -I to provide host headers without
having to resolve the IP.

So right now your request is equivalent to this (NB: the port is glued
to the path because it's not starting with a /):

http://172.18.20.5:8080https://www.xxxx.yyyy.com

It appears that at least some web servers accept full URIs in the GET
request, strip protocol/hostname part and take the URL at the end (or
"/" of there no URL), which explains why you get 200 OK.

BTW you can use "-vvv" to print all debug output...
