How to set 'X-Frame-Options' on iframe?

Question

If I create an iframe like this:

var dialog = $('<div id="' + dialogId + '" align="center"><iframe id="' + frameId + '" src="' + url + '" width="100%" frameborder="0" height="'+frameHeightForIe8+'" data-ssotoken="' + token + '"></iframe></div>').dialog({

How can I fix the error:

Refused to display 'https://www.google.com.ua/?gws_rd=ssl' in a frame because it set 'X-Frame-Options' to 'SAMEORIGIN'.

with JavaScript?

Answer 1

You can't set X-Frame-Options on the iframe. That is a response header set by the domain from which you are requesting the resource (google.com.ua in your example). They have set the header to SAMEORIGIN in this case, which means that they have disallowed loading of the resource in an iframe outside of their domain. For more information see The X-Frame-Options response header on MDN.

A quick inspection of the headers (shown here in Chrome developer tools) reveals the X-Frame-Options value returned from the host.

Answer 2

X-Frame-Options is a header included in the response to the request to state if the domain requested will allow itself to be displayed within a frame. It has nothing to do with javascript or HTML, and cannot be changed by the originator of the request.

This website has set this header to disallow it to be displayed in an iframe. There is nothing that can be done in a client-side web browser to stop this behaviour.

Answer 3

In case you are in control of the Server that sends the content of the iframe you can set the setting for X-Frame-Options in your webserver.

Configuring Apache

To send the X-Frame-Options header for all pages, add this to your site's configuration:

Header always append X-Frame-Options SAMEORIGIN

Configuring nginx

To configure nginx to send the X-Frame-Options header, add this either to your http, server or location configuration:

add_header X-Frame-Options SAMEORIGIN;

No configuration

This header option is optional, so if the option is not set at all, you will give the option to configure this to the next instance (e.g. the visitors browser or a proxy)

Answer 4

Since the solution wasn't really mentioned for the server side:

One has to set things like this (example from apache), this isn't the best option as it allows in everything, but after you see your server working correctly you can easily change the settings.

           Header set Access-Control-Allow-Origin "*"
           Header set X-Frame-Options "allow-from *"

Answer 5

and if nothing helps and you still want to present that website in an iframe consider using X Frame Bypass Component which will utilize a proxy.

Answer 6

not really... I used

 <system.webServer>
     <httpProtocol allowKeepAlive="true" >
       <customHeaders>
         <add name="X-Frame-Options" value="*" />
       </customHeaders>
     </httpProtocol>
 </system.webServer>

Answer 7

The X-Frame-Options HTTP response header can be used to indicate whether or not a browser should be allowed to render a page in a <frame>, <iframe> or <object>. Sites can use this to avoid clickjacking attacks, by ensuring that their content is not embedded into other sites.

For More Information: https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/X-Frame-Options

I have an alternate solution for this problem, which I am going to demonstrate by using PHP:

iframe.php:

<iframe src="target_url.php" width="925" height="2400" frameborder="0" ></iframe>

target_url.php:

<?php 
  echo file_get_contents("http://www.example.com");
?>

This is also a new browser security feature to prevent phishing and other security threats. For chrome, you can download an extension to prevent the browser from denying the request. I encountered this issue while working on WordPress locally.

I use this extension https://chrome.google.com/webstore/detail/ignore-x-frame-headers/gleekbfjekiniecknbkamfmkohkpodhe

Answer 9

(I'm resurrecting this answer because I would like to share the workaround I created to solve this issue)

If you don't have access to the website hosting the web page you want to serve within the <iframe> element, you can circumvent the X-Frame-Options SAMEORIGIN restrictions by using a CORS-enabled reverse proxy that could request the web page(s) from the web server (upstream) and serve them to the end-user.

Here's a visual diagram of the concept:

Since I was unhappy with the CORS proxies I found, I ended up creating one myself, which I called CORSflare: it has been designed to run in a Cloudflare Worker (serverless computing), therefore it's a 100% free workaround - as long as you don't need it to accept more than 100.000 request per day.

You can find the proxy source code on GitHub; the full documentation, including the installation instruction, can be found in this post of my blog.

Answer 10

For this purpose you need to match the location in your apache or any other service you are using

If you are using apache then in httpd.conf file.

  <LocationMatch "/your_relative_path">
      ProxyPass absolute_path_of_your_application/your_relative_path
      ProxyPassReverse absolute_path_of_your_application/your_relative_path
   </LocationMatch>

Answer 11

The solution is to install a browser plugin.

A web site which issues HTTP Header X-Frame-Options with a value of DENY (or SAMEORIGIN with a different server origin) cannot be integrated into an IFRAME... unless you change this behavior by installing a Browser plugin which ignores the X-Frame-Options Header (e.g. Chrome's Ignore X-Frame Headers).

Note that this not recommended at all for security reasons.

Answer 12

you can set the x-frame-option in web config of the site you want to load in iframe like this

<httpProtocol>
    <customHeaders>
      <add name="X-Frame-Options" value="*" />
    </customHeaders>
  </httpProtocol>

Answer 13

You can not really add the x-iframe in your HTML body as it has to be provided by the site owner and it lies within the server rules.

What you can probably do is create a PHP file which loads the content of target URL and iframe that php URL, this should work smoothly.
