Allowing cross origin requests for http and https
My website supports both http and https protocols. However using the code below in .htaccess file, I can only set one domain to allow CORS requests:
Header set Access-Control-Allow-Origin: http://example.com
I want to allow CORS for both http and https versions of my site (not just "*") and tried the solutions here: Access-Control-Allow-Origin Multiple Origin Domains?
But the problem is that all solutions rely on Origin header in the request which may not exist and also is not secure. (anyone can put a origin header in their request)
I want to know if the request has been served over https and use this info to set the proper CORS header. Something like this:
SetEnvIf servedOverHttps httpsOrigin=true
Header set Access-Control-Allow-Origin: https://example.me env=httpsOrigin
SetEnvIf notServedOverHttps httpOrigin=true
Header set Access-Control-Allow-Origin: http://example.me env=httpOrigin
How can I find out that it's a https request?
Have you tried using HTTPS variable?
It will be set to "on" for all https requests. Your .htaccess should look like this
Header set Access-Control-Allow-Origin: http://example.com #default
Header set Access-Control-Allow-Origin: https://example.com env=HTTPS #override if https
