I\'m writing a tiny webpage whose purpose is to frame a few other pages, simply to consolidate them into a single browser window for ease of viewing. A few of the pages I\'
Edit .htaccess if you want to remove X-Frame-Options from an entire directory.
And add the line: Header always unset X-Frame-Options
[contents from: Overcoming "Display forbidden by X-Frame-Options"
UPDATE 2019: You can bypass X-Frame-Options
in an <iframe>
using just client-side JavaScript and my X-Frame-Bypass Web Component. Here is a demo: Hacker News in an X-Frame-Bypass. (Tested in Chrome & Firefox.)
Solution for loading an external website into an iFrame even tough the x-frame option is set to deny on the external website.
If you want to load a other website into an iFrame and you get the Display forbidden by X-Frame-Options”
error then you can actually overcome this by creating a server side proxy script.
The src
attribute of the iFrame could have an url looking like this: /proxy.php?url=https://www.example.com/page&key=somekey
Then proxy.php would look something like:
if (isValidRequest()) {
echo file_get_contents($_GET['url']);
}
function isValidRequest() {
return $_SERVER['REQUEST_METHOD'] === 'GET' && isset($_GET['key']) &&
$_GET['key'] === 'somekey';
}
This by passes the block, because it is just a GET request that might as wel have been a ordinary browser page visit.
Be aware: You might want to improve the security in this script. Because hackers could start loading in webpages via your proxy script.
FWIW:
We had a situation where we needed to kill our iFrame
when this "breaker" code showed up. So, I used the PHP function get_headers($url);
to check out the remote URL before showing it in an iFrame
. For better performance, I cached the results to a file so I was not making a HTTP connection each time.
It appears that X-Frame-Options Allow-From https://... is depreciated and was replaced (and gets ignored) if you use Content-Security-Policy header instead.
Here is the full reference: https://content-security-policy.com/
The only real answer, if you don't control the headers on your source you want in your iframe, is to proxy it. Have a server act as a client, receive the source, strip the problematic headers, add CORS if needed, and then ping your own server.
There is one other answer explaining how to write such a proxy. It isn't difficult, but I was sure someone had to have done this before. It was just difficult to find it, for some reason.
I finally did find some sources:

^ preferred. If you need rare usage, I think you can just use his heroku app. Otherwise, it's code to run it yourself on your own server. Note sure what the limits are.
whateverorigin.org
^ second choice, but quite old. supposedly newer choice in python: https://github.com/Eiledon/alloworigin
then there's the third choice:
http://anyorigin.com/
Which seems to allow a little free usage, but will put you on a public shame list if you don't pay and use some unspecified amount, which you can only be removed from if you pay the fee...
