在https页面的iframe中加载http页面

Question

I have a page in a https site say https://www.example.com which contains an iframe that points to another php page target.php in same site .

<iframe src="/target.php"></iframe> 

This target.php is redirecting the request to another http url using

header("Location: http://demosite/page"  ,TRUE, 307) 

Unfortunately , this redirection to http site is not working from the https iframe . Although it works from iframe in http page .

I have tried

file_get_contents("http://demosite/page") 

and curl in target.php (instead of header redirection) . Those did not return the page in proper format .

Please can someone advise me how to display a http page in an iframe of https page.

Thanks in advance .

Answer 1

Leave out the protocol in the redirection. Then it will automatically use the same protocol that was used to access target.php :

header("Location: //demosite/page", true, 307);
