Overcoming "Display forbidden by X-Frame-Options"

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'm trying to frame forbid being framed and throw a "Refused to display document because display forbidden by X-Frame-Options." error in Chrome. I understand that this is a security limitation (for good reason), and don't have access to change it.

Is there any alternative framing or non-framing method to display pages within a single window that won't get tripped up by the X-Frame-Options header?

What happens if X-Frame-options is not set?

When X-Frame-Options Header is not set your application pages can be embedded within any other website with no restrictions, e.g. to create a malicious page with your original content augmented with dangerous fragments including phishing attempts, ads, clickjacking code, etc.

How do I change the X Frame option?

Double-click the HTTP Response Headers icon in the feature list in the middle. In the Actions pane on the right side, click Add. In the dialog box that appears, type X-Frame-Options in the Name field and type SAMEORIGIN in the Value field. Click OK to save your changes.

What does X-Frame-options SAMEORIGIN mean?

X-Frame-Options:SAMEORIGIN - This means that the page can only be embedded in a frame on a page with the same origin as itself. X-Frame-Options:ALLOW-FROM - The page can only be displayed in a frame on the specified origin. This only works in browsers that support this header.

What is X Frame bypass?

X-Frame-Bypass is a Web Component, specifically a Customized Built-in Element, which extends an IFrame to bypass the X-Frame-Options: deny/sameorigin response header. Normally such headers prevent embedding a web page in an <iframe> element, but X-Frame-Bypass is using a CORS proxy to allow this.

I had a similar issue, where I was trying to display content from our own site in an iframe (as a lightbox-style dialog with Colorbox), and where we had an server-wide "X-Frame-Options SAMEORIGIN" header on the source server preventing it from loading on our test server.

This doesn't seem to be documented anywhere, but if you can edit the pages you're trying to iframe (eg., they're your own pages), simply sending another X-Frame-Options header with any string at all disables the SAMEORIGIN or DENY commands.

eg. for PHP, putting

<?php     header('X-Frame-Options: GOFORIT');  ?> 

at the top of your page will make browsers combine the two, which results in a header of

X-Frame-Options SAMEORIGIN, GOFORIT 

...and allows you to load the page in an iframe. This seems to work when the initial SAMEORIGIN command was set at a server level, and you'd like to override it on a page-by-page case.

All the best!
