PHP Why the difference when using http before $SERVER variables?

I've googled and googled and am stumped.

I am trying to capture the url of a page after logging into the proxy

url of page before proxy login:

https://example.org/mypage.php

url of page after proxy login:

https ://example-org.proxy.example.org/mypage.php

When I try to capture the url using

$lnk = "https ://$_SERVER['HTTP_HOST']$_SERVER['REQUEST_URI']";

the output is as desired: 

https ://example-org.proxy.example.org/mypage.php

When I leave off the https:// and just capture the $SERVER variables the output lacks the proxy part of the url. 

$lnk = $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];

output: 

example.org/mypage.php

The latter makes sense as if I dump the $SERVER array I see that the the proxy part of the url missing. How is it finding the proxy info in the first example?

Update:
I've used an incogneto window in Chrome and tried it on IE, same behavior. I tried the following
$lnk = $_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
$lnk2 = "https://".$lnk;

echoing out both variables give the same results as above. If I change the http:// to 'bla' or 'bla://' $lnk and $lnk2 both show the expected non proxied url. It appears that http:// and https:// are changing this somehow and for the life of me I can't figure out how.

Turns out the proxy was likely doing a search and replace on the stream. I added a couple of lines of code to print the contents of $lnk2 to a file right after creation and sure enough it lacked the proxied url as expected. Glad to know I wasn't going crazy.
