Hello,

I have a project where we are trying to load a thirdparty site into an IFRAME inside EO WebBrowser. We are trying to override/ignore the X-Frame-Options SAMEORIGIN security setting but the browser control does not seem to respect the fact we have EnableWebSecurity=False and EnableXSSAuditor=False set in the code.

We are using this code to set up the browser --

Dim bo As New BrowserOptions
bo.EnableWebSecurity = False
bo.EnableXSSAuditor = False
EO.WebEngine.Engine.Default.Options.SetDefaultBrowserOptions(bo)

Dim wv As New WebView
wv.SetOptions(bo)

WebControl1.WebView = wv

When we attempt to load the site into the IFRAME we get the following "Refused to display" error



Is this a bug in webview or is there another option I need to toggle to allow the IFRAME to display?

Thanks

Ron

Hello,

we're are using EO.Total 18.2.53.0. Is there any way in that version to bypass x-frame-options/sameorigin?

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. 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 . 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. So you cannot embed their website into yours. Browsers when see that the response header contains X-Frame-Options: SAMEORIGIN, they check your domain and block the rendering of the <iframe>. It is a security measure to avoid clickjacking.
