As i posted in my answer, the $_SERVER["HTTPS"] shows whether the server who send the request was using HTTPS. – MadsBjaerge Feb 02 '15 at 10:36

Check for $_SERVER["SERVER_PORT"] if its 80, then its a simple request, if 443 or secure protocol's port then its https.
And maybe UseCanonicalPhysicalPort = On has to set on Apache2.

But u wont set secure protocol to 80 :P And configure by the script owner in good case. So it will be synced. – Tamás Szabó Feb 02 '15 at 10:29

No, but you could use port 993, 443, etc etc, so'll the answer i gave will tell you :) $_SERVER["https"] – MadsBjaerge Feb 02 '15 at 10:30

From the manual, it seems that $_SERVER contains an indication whether this is HTTP or not.
'HTTPS' Set to a non-empty value if the script was queried through the HTTPS protocol. Note: Note that when using ISAPI with IIS, the value will be off if the request was not made through the HTTPS protocol.
So checking $_SERVER["HTTPS"] should be okay, i dont have any idea whether this can be trusted or not.

"'HTTPS' Set to a non-empty value if the script was queried through the HTTPS protocol", so if the request is from a server running HTTPS, it the value would be set to a non-empty value. – MadsBjaerge Feb 02 '15 at 12:33

Chauhan,
it's possible via PHP Global variable. you have uses $_SERVER['HTTP_REFERER'] variable in second.com. it will return http request url.
Learn more for php global variable visit http://php.net/manual/en/reserved.variables.server.php
